Marrying an Illegal Immigrant

You married, or you are about to marry, someone who came into the United States without papers. You want to know whether the marriage changes anything, what you can file, and whether filing could make things worse. I have practiced immigration law since 1996, and since founding this firm in 2001 I have helped many couples in exactly this position. Some had a clear road. Some had a hard one. A few had no marriage-based road at all, and the most useful thing I could do was tell them so before they paid anyone to file.

The short answer

Marrying an undocumented immigrant is legal, and the marriage by itself changes nothing about your spouse’s immigration status. What the marriage does is let you, as a U.S. citizen, file a petition for your spouse. For a spouse who entered the United States without inspection, the usual road has three steps: your petition (Form I-130), a waiver of the unlawful-presence bar filed from inside the United States (Form I-601A), and an immigrant visa interview at a U.S. consulate abroad. Whether that road exists for your spouse depends on what the government’s records show about how and when your spouse crossed the border. That is why we check the record before anything is filed.

How your spouse came in	What usually follows (checked November 7, 2026)
Crossed once without inspection, no other border history	I-130, then I-601A waiver, then the consular interview
Crossed without inspection, but has an old petition filed for them on or before April 30, 2001, or is a military family member	Possibly a green card without leaving the United States (§ 245(i) or military parole in place)
Was caught at the border and sent back, then crossed again; or used a U.S. citizen’s papers; or crossed back in after more than a year here	Possibly a permanent bar that marriage cannot fix; we need the record first
Came in with a visa or was inspected at a port, then stayed too long	A different and usually easier road; this page is not about you (see the next box)

What we mean by these words

On this page, “illegal immigrant,” “undocumented immigrant” and “entered without inspection” (often shortened to EWI) all describe the same situation from different angles: a person who is not a U.S. citizen, has no permission to be here, has no immigration documents, and was never admitted or paroled into the United States. Most often that person came in away from a port of entry, alone or with a smuggler (in Mexico, commonly called a coyote). Some public usage, and some government rhetoric, lumps everyone without status together. Immigration law does not. Its organizing idea is admission: a person who was inspected and admitted and then stayed past their permitted time is an overstay, and the law treats that person very differently. So we define the words.

Being smuggled in is not, by itself, the “smuggling” ground of inadmissibility that people fear. That ground reaches someone who helped another person enter illegally (INA § 212(a)(6)(E)). If your spouse ever helped a relative or anyone else cross, read our guide on what to check before leaving for the consular interview, which covers that trap.

Came in with a visa and overstayed? Do not leave the country before you get advice.

If your spouse was inspected and admitted (a visa, a visitor’s admission, or a border crossing card at a port of entry) and then stayed too long, the spouse of a U.S. citizen can usually apply for the green card inside the United States through adjustment of status. Adjustment has always been discretionary, and since a May 21, 2026 USCIS memo (PM-602-0199) officers weigh that discretion much more heavily (our page on the USCIS discretion memo explains what that means in practice). The danger is the reverse of the one on this page: an overstay who reads “your spouse must leave and interview abroad” and leaves can create the 10-year bar they would otherwise never face. And as of November 2026, USCIS policy is to issue a Notice to Appear in immigration court when it denies a benefit request from someone who is not lawfully present, so a weak filing has a real downside. Our page on removal proceedings explains how a denial can lead to court.

Can a U.S. citizen legally marry an undocumented immigrant?

Yes. Marriage is governed by state law, and states do not ask about immigration status. In Montana, for example, the clerk of the district court issues a marriage license on proof of age and proof that the marriage is not prohibited (MCA 40-1-202), and the list of prohibited marriages (an existing marriage, close relatives) says nothing about citizenship (MCA 40-1-401). A foreign passport or consular identification card usually serves as identification.

For immigration purposes the marriage must also be genuine. A petition for a spouse fails if the marriage was entered to get immigration benefits, and a person found to have entered such a marriage can never again be the beneficiary of a family or employment petition (INA § 204(c)). A real marriage is the starting point, not the finish line. Our page on marriage-based green cards covers how couples prove it.

If you marry an illegal immigrant, do they become legal?

No. Nothing changes on the wedding day, and nothing changes while the paperwork is pending. Your spouse becomes a permanent resident only at the end of a petition and green card process. In the meantime your spouse has no status, no work permit from the marriage, and no protection from arrest. That includes the waiver stage: the regulation says plainly that a pending or approved provisional waiver gives no lawful status and does not protect a person from removal proceedings or removal (8 CFR 212.7(e)(2)(i), paraphrased). Couples should plan their lives around that fact, not around the hope that a receipt notice is a shield.

What are the steps for a spouse who entered without inspection?

For most U.S. citizens married to someone who entered without inspection, the road has three steps, and a fourth that comes first.

Step 0: check the record

Before we file anything, we find out what the government’s files say about your spouse’s border history. The reasons are explained in the section on checking the record below.

Step 1: the I-130 petition

You file Form I-130, Petition for Alien Relative, to prove that you are a U.S. citizen and that the marriage is real. The spouse of a U.S. citizen is an “immediate relative,” so there is no waiting line for a visa number once the petition is approved. A spousal petition is not a discretionary decision: the USCIS Policy Manual says that USCIS generally cannot deny a family-based petition as a matter of discretion (6 USCIS-PM B.5, paraphrased). It is decided on your status and the relationship.

Step 2: the I-601A provisional waiver

Here is the problem the waiver solves. A person who has been unlawfully present in the United States for one year or more, and then leaves, is barred from returning for ten years (INA § 212(a)(9)(B)(i)(II)); between 180 days and a year, the bar is three years. For someone who entered without inspection, the unlawful-presence clock generally runs from the day of entry, but never from earlier than April 1, 1997. Time before age 18 does not count toward these two bars, and there are a few other narrow exceptions. The bar is triggered by the departure. And your spouse must depart, because without § 245(i) or parole in place a person who was never admitted or paroled cannot adjust status here (INA § 245(a)).

The I-601A lets your spouse ask USCIS to waive that bar before leaving. Your spouse must show that you, the U.S. citizen spouse, would suffer extreme hardship if the waiver were denied. A U.S. citizen or permanent-resident spouse or parent can be the qualifying relative; a U.S. citizen child cannot (INA § 212(a)(9)(B)(v)). The I-130 must be approved and the State Department’s immigrant visa processing fee paid before the I-601A is filed, and the I-601A covers only the unlawful-presence bar (8 CFR 212.7(e)). If anything else is wrong (a permanent bar, fraud, a criminal ground, a five-year bar for missing a court hearing) the provisional waiver does not reach it. Our I-601A guide covers eligibility, the hardship standard and the evidence in depth.

Step 3: the immigrant visa interview abroad

With the waiver approved, your spouse completes consular processing through the National Visa Center and attends an immigrant visa interview at a U.S. embassy or consulate. In our cases, Mexican spouses interview at the U.S. Consulate General in Ciudad Juárez, with a medical examination by a consulate-approved panel physician beforehand. If the visa is issued, your spouse returns and is admitted as a permanent resident. The consular officer decides admissibility at the interview, so anything the I-601A did not cover is decided there. Our guide to leaving for the consular interview with an approved I-601A lists what to check before your spouse travels.

Can my undocumented spouse get a green card without leaving the United States?

Usually not, but there are three exceptions worth checking.

• Section 245(i). A person who is the beneficiary of a family or employment petition, or a labor certification, filed on or before April 30, 2001, may be “grandfathered.” That includes a person who was then the spouse or child of the beneficiary, so a parent’s old petition can count. If the petition was filed after January 14, 1998, the person must also have been physically present in the United States on December 21, 2000. The petition had to be approvable when filed (8 CFR 245.10(a)). A grandfathered person can adjust status here on a later, different petition (including yours) by paying an extra $1,000 sum set by statute; the old petition does not have to be the one that leads to the green card (7 USCIS-PM C.2). The 2001 date is not “any marriage before 2001”; it is a petition filed by then. And § 245(i) does not cure the permanent bars described below: a grandfathered spouse who re-entered illegally after a removal, or after more than a year here, still cannot adjust (Matter of Briones, 24 I&N Dec. 355 (BIA 2007)).
• Military parole in place. The spouse of an active-duty service member, a member of the Selected Reserve, or a veteran who was not dishonorably discharged may ask USCIS for parole in place, which counts as a parole and opens adjustment of status. It is a discretionary policy, available as of November 2026; confirm it before relying on it. Our parole in place page explains who qualifies.
• Cancellation of removal, in court only. A spouse who has lived here continuously for ten years and is placed in removal proceedings may be able to ask an immigration judge for non-LPR cancellation of removal, which requires exceptional and extremely unusual hardship to a U.S. citizen or permanent-resident spouse, parent or child. It is a defense, not an application you can file.

One program is gone. “Keeping Families Together,” the 2024 parole program for spouses of U.S. citizens, was set aside and vacated by a federal court in Texas on November 7, 2024 (Texas v. Department of Homeland Security, No. 6:24-cv-00306 (E.D. Tex.)). As of November 2026, it is not available.

Why do we check the government’s record before filing anything?

Because people remember border events differently from how they were recorded, and the record decides the case. A spouse may say “they caught me and sent me back” about an event that was, on paper, a formal expedited removal order, or a withdrawal with no order at all. A person who was fingerprinted at the border twenty years ago may not know it. A client who did not mention something at the first meeting may mention it at the consular interview, which is the worst place to learn it.

I learned this the hard way. Years ago a client of ours was denied at the consulate after an I-601A approval because he had been removed at the border and had come back in quickly, which is a permanent bar, and he had never told us. Since then, before we start any I-130, I-601A and consular sequence, we request the client’s fingerprint record from the Department of Homeland Security’s biometric identity office (OBIM), and we add CBP or other records requests where the facts call for it. It costs a few months. It is far cheaper than a denial abroad.

A petition filed without that check also has a downside here. As of November 2026, USCIS policy is to issue a Notice to Appear when it denies a benefit request and the person is not lawfully present (USCIS PM-602-0187, § VI). Our reading (an inference, not a stated rule for spousal petitions) is that a denied filing tied to an undocumented spouse can put that spouse’s name in front of the agency in the worst possible way.

When can marriage not help? The permanent bars

Some border histories close the marriage road completely, and no waiver available to a spouse opens it. Three questions decide whether your spouse is in that group.

Question 1: what document was used?

Many spouses first tried to come in at a port of entry with someone else’s papers. Which papers matters enormously.

• A U.S. passport, U.S. passport card or U.S. birth certificate belonging to someone else is a false claim to U.S. citizenship. A person who falsely claims citizenship “for any purpose or benefit” under federal or state law, including to get into the country, is inadmissible permanently, and there is no waiver (INA § 212(a)(6)(C)(ii)). The federal appeals court for Montana has held that presenting a false U.S. birth certificate to a border officer to get in is exactly that (Valadez-Munoz v. Holder, 623 F.3d 1304, 1308–09 (9th Cir. 2010); see also Ramirez Munoz v. Garland, 71 F.4th 1174 (9th Cir. 2023)), and the USCIS Administrative Appeals Office has refused relief to people who presented another person’s U.S. passport at entry, because no waiver exists (non-precedent; for example, Matter of Y-Z-, FEB062019_01H5212 (AAO Feb. 6, 2019), denying a motion). Two limits: this permanent bar applies to false claims made on or after September 30, 1996, and an earlier false claim is treated as a waivable misrepresentation (8 USCIS-PM K.2); and there is a narrow exception for a person whose parents were both citizens, who lived here before turning 16, and who reasonably believed they were a citizen.
• A foreign passport, visa or border crossing card belonging to someone else is fraud or misrepresentation (INA § 212(a)(6)(C)(i)), not a false claim to citizenship. That ground can be waived, but only on Form I-601 after the consular officer finds it, and only on extreme hardship to a U.S. citizen or permanent-resident spouse or parent (INA § 212(i)(1)). It also makes the I-601A unavailable, because the provisional waiver is only for a person whose sole problem is unlawful presence (8 CFR 212.7(e)).

Question 2: what did “turned back” mean on paper?

Since April 1, 1997, a person caught at a port with false papers is often ordered removed on the spot under expedited removal; the officer records a sworn statement and serves Form I-860, Notice and Order of Expedited Removal (8 CFR 235.3(b)(2)(i)). That is a removal order. Sometimes the officer instead lets the person withdraw the application for admission and go back, which is not an order (8 CFR 235.4). And sometimes, especially away from ports, the person was simply returned with no paperwork at all.

The difference is decisive. A person who was ordered removed (including by expedited removal) and then enters or tries to enter again without being admitted is permanently barred (INA § 212(a)(9)(C)(i)(II)). The order can also be reinstated without a new hearing (INA § 241(a)(5)). A withdrawal with no order does not trigger that bar, though the document question above still applies.

Question 3: did your spouse cross back in after more than a year here?

A person who was unlawfully present for more than one year in total, left, and then entered or tried to enter again without being admitted is also permanently barred (INA § 212(a)(9)(C)(i)(I)). This is the trap for a spouse who went home for a parent’s funeral and walked back in. Unlike the three- and ten-year bars, time under 18 is not excluded from this one. Only time after April 1, 1997 counts, and the return must also have been after that date (9 FAM 302.11-4(B)(1)). Our page on unlawful presence explains how the time adds up.

What “permanent” means

For the two § 212(a)(9)(C) bars, “permanent” means the spouse must remain outside the United States for at least ten years after the last departure and then obtain permission to reapply before returning (INA § 212(a)(9)(C)(ii)); our page on permission to reapply after deportation explains that process. The only waiver is a discretionary one for VAWA self-petitioners who show a connection between the abuse and their removal, departure or re-entry (INA § 212(a)(9)(C)(iii)). A false claim to citizenship has no ten-year exit at all.

An example: a permanent bar for two reasons

Here is a constructed example built on a pattern we have seen. A young man tries to enter at a port of entry with a relative’s U.S. passport card. The officers catch it, take a sworn statement, and send him back across under an expedited removal order. Weeks later he crosses without inspection. Years later he marries a U.S. citizen, and they come to us. The record shows two independent permanent bars: the false claim to U.S. citizenship (no waiver, no exit) and the removal order followed by an unlawful return (ten years outside and permission to reapply). Either alone would close the marriage road. I had never before seen a case with both, and it is the reason this section exists.

What remains when marriage cannot help

For most families in this group, the honest answer is that there is nothing marriage-based to file. A few other doors exist, each narrow:

• U visa. A victim of a qualifying crime who helped law enforcement can ask for a waiver of nearly every inadmissibility ground, including both permanent bars and a false claim to citizenship (INA § 212(d)(14)). See our U visa page.
• VAWA. A spouse abused by the U.S. citizen or permanent-resident spouse can self-petition, and the § 212(a)(9)(C) waiver is available in that setting, but it does not reach a false claim to citizenship. See our VAWA self-petition overview.
• Asylum, withholding of removal or protection under the Convention Against Torture are separate, fear-based protections with their own requirements. They are not a workaround for a marriage case.

Paying someone to file a marriage case anyway is harmful, not just wasteful. A denied filing can lead to a Notice to Appear, and a filing that misstates the border history adds a misrepresentation problem to the bar. We have written about the operations that file weak cases at scale and what they cost families.

What else can change the answer?

An old removal order or a missed court hearing

A spouse ordered removed by an immigration judge (often in absentia, for missing a hearing) faces two separate problems. Leaving the country carries out the order and triggers a separate ten-year bar on return (INA § 212(a)(9)(A)), which Form I-212, permission to reapply, can overcome; a person with a final order must have the I-212 approved before filing the I-601A (8 CFR 212.7(e)(4)(iv)). Separately, for proceedings begun on or after April 1, 1997, missing the hearing without reasonable cause makes the person inadmissible for five years after leaving (INA § 212(a)(6)(B); 9 FAM 302.9-3(B)(1)). There is no waiver of that five-year bar for an immigrant visa, and the I-212 does nothing about it. Sometimes the better course is a motion to reopen the old case. Our I-212 guide and our guide to appeals and motions to reopen cover both.

A criminal record or a fraud ground

A criminal ground or a fraud ground is not covered by the I-601A. It is waived, if at all, on Form I-601 after the consular officer finds it. For a misrepresentation, the qualifying relative is a U.S. citizen or permanent-resident spouse or parent; for most criminal grounds, it is a spouse, parent, son or daughter, under the § 212(h) waiver. Our overview of immigration waivers sets out the qualifying relatives ground by ground.

A constructed example shows how much the details matter. A man had an old relative petition, filed for him before April 30, 2001, that kept § 245(i) alive. Years later a different family member petitioned for him, and he applied to adjust status here. At the interview he disclosed, for the first time, that he had once crossed at a port using someone else’s foreign passport and visa. That is a misrepresentation, not a false claim to citizenship, so it could be waived. But the § 212(i) waiver counts hardship only to a citizen or permanent-resident spouse or parent, so the family member who petitioned could not carry it; a permanent-resident parent could. We filed the I-601 on that basis and it was approved. Three lessons follow for a marriage case: the document decides the bar; in a marriage case the U.S. citizen spouse is the qualifying relative for the fraud waiver, and U.S. citizen children are not, except in a VAWA self-petition; and the I-601 is decided after the ground is found, never in advance like the I-601A.

A spouse in immigration court now

If your spouse is in removal proceedings, the timing of the marriage and the court’s role change everything. Read our page on marriage during removal proceedings before anything is filed.

Travel on advance parole

For the rare spouse who can adjust inside the United States (for example under § 245(i)), travel is a trap. Since the Board of Immigration Appeals decided Matter of Delcarmen-Lara, 29 I&N Dec. 830 (BIA 2026) on August 13, 2026, leaving on advance parole is a departure that can trigger the unlawful-presence bars. Read our advance parole page before any trip.

What if I am a permanent resident, not a citizen?

A green card holder can also petition for a spouse, in the F2A category. Three differences matter.

• There is a line. F2A spouses wait for a visa number. As of the November 2026 Visa Bulletin, the F2A final action date is October 22, 2026 for most countries and April 22, 2026 for Mexico, so the wait is currently short; it moves, so check the current Visa Bulletin. During the wait your spouse is still undocumented and still exposed.
• A lawful entry is not enough. A permanent resident’s spouse who came in with a visa but fell out of status, or worked without permission, generally cannot adjust here either, because only immediate relatives of citizens are exempt from those bars (INA § 245(c)(2)). So most F2A spouses who are out of status take the same three-step road described above.
• The waiver still works. A permanent-resident spouse can be the qualifying relative for the I-601A and the I-601. And if you become a citizen before your spouse’s case finishes, your spouse becomes an immediate relative, which can remove the wait and, for an overstay, open adjustment of status.

Can a felon marry an undocumented immigrant?

Yes. A criminal record does not prevent a marriage, and for most crimes it does not by itself stop a citizen’s petition for a spouse. The one bar the petition statute writes in is the Adam Walsh Act: a citizen or permanent resident convicted of a “specified offense against a minor” cannot petition for a relative unless DHS, in its sole and unreviewable discretion, finds the petitioner poses no risk to the beneficiary (INA § 204(a)(1)(A)(viii) and (B)(i)(II)). Outside that, a spousal petition turns on the petitioner’s status and the marriage, not on discretion.

A criminal record matters in other ways:

• Fiancé(e) petitions are different. For a K-1 petitioner who has filed before, the waiver of the multiple-filing limits is generally not granted to a petitioner with a record of violent criminal offenses against a person, except in extraordinary circumstances (INA § 214(d)(2)), and the State Department shares a K petitioner’s criminal background information with the beneficiary (8 U.S.C. § 1375a(a)(5)(A)(iii)). Marrying first and filing an I-130 avoids those K-1 rules.
• The affidavit of support. You must still file Form I-864 and meet the income requirement, or find a joint sponsor. A petitioner who is incarcerated, or recently released with little income, usually needs one.
• Your spouse’s own record matters most. Your spouse’s crimes, not yours, decide admissibility.

How we can help

We start with what the government’s records say, not with a form. In a consultation we sort your spouse into one of the groups on this page, tell you which bars apply and which do not, and, if the road is open, lay out the I-130, I-601A and consular steps with a realistic timeline. If the road is closed, we tell you that too, and why, so that you do not spend money on a filing that can only hurt. We serve couples across Montana, North Dakota, Wyoming and the Rocky Mountain West. Contact us to schedule a consultation.
