Can an Undocumented Immigrant Marry a U.S. Citizen?

If you are an undocumented immigrant in the United States (sometimes referred to as an "illegal alien"), nothing stops you from marrying a U.S. citizen, or most anyone else you wish to marry. U.S. citizens marry illegal immigrants on a regular basis. The main limitations on marriage in the United States have to do with age and whether the person one wishes to marry is a close relative. In California, for example, you must be at least 18 years old to marry, unless you have parental consent.

Whether your marriage to a U.S. citizen will get you a green card (U.S. lawful permanent residence) is, however, another matter. In theory, immigrant spouses are "immediate relatives," and are eligible for a green card through the marriage. But undocumented immigrants face high hurdles in claiming this right, as discussed below.

Problem of Inadmissibility for People Who've Lived Illegally in the U.S.

Despite the fact that your marriage to a U.S. citizen might be valid, when an illegal immigrant seeks to become a legal resident, various issues come up. The biggest concern is how much time the non-citizen spent without legal documents in the United States, particularly if they entered the country without permission or inspection (for example, they crossed the border illegally).

If you have spent more than 6 months (180 days) here after an illegal entry, and you apply for a green card, you could encounter problems when (as is likely) you have to travel to a consulate outside the United States for your green card interview. There, you could be penalized for your illegal entry and stay. The penalty for an unlawful stay of between 180 and 365 days is having to spend 3 years outside the United States before returning. If you have spent more than 1 year in the U.S. unlawfully, you'll need to spend 10 years outside the United States before returning. For details, see Understanding the Three and Ten-Year Bars for Unlawful Presence. You might be able to get a "waiver" (legal forgiveness) of your illegal stay before leaving for the consulate using Form I-601A, but these waivers are hard to get approved for and depend on proving hardship to your U.S. family members.

Unfortunately, illegal entrants for the most part have no right to "adjust status," that is, file all green card paperwork and attend the interview, within the United States. That's especially unfortunate because staying in the United States for the whole application process would avoid this inadmissibility problem. There are a few narrow exceptions, however, allowing people who fall under an old law called 245(i) to adjust status; to find out who this works for, see Adjustment of Status to Permanent Resident - FAQ.

Immigrants who entered the United States (on their most recent entry) with a visa or other valid paperwork and are married to a U.S. citizen don't, however, have any problem with using the adjustment of status procedure. That's because they are allowed to submit all their paperwork within the United States and attend their interview here—which means they can't be penalized by being barred from returning to the United States, because they never left. (They could face a separate problem, however, if they used a visa meant for a limited purpose, such as tourism, with the secret idea of marrying a U.S. citizen and getting a green card. That's visa fraud, and can lead to green card denial.)

Meeting Other Criteria for Getting Green Card Through Marriage to a U.S. Citizen

Of course, to get a green card based on marriage to a U.S. citizen, you would also have to prove that you meet all the various other eligibility criteria, such as that it is a valid (legally recognized) marriage and that it's "bona fide" marriage (not just a fraudulent, possibly paid arrangement to get you a green card).

You would also have to overcome any other possible grounds of inadmissibility, by showing, for example, that you haven't committed certain types of crimes (or more than two of any crimes), don't have a communicable disease that would present a danger within the United States, and won't require need-based public assistance such as food stamps (sometimes called welfare). But as mentioned above, these are the least of your worries if you entered the United States without a visa.

Issue of Filing the Initial Paperwork While in the United States Illegally

In order to start the immigration process, the U.S. citizen would need to submit a petition on Form I-130 to U.S. Citizenship and Immigration Services (USCIS). That form asks for biographical information regarding both the U.S. petitioner and the immigrant, including current address. In past years, immigration enforcement authorities did not use this information to track down and arrest immigrants. But it has always been true that even if USCIS approves the I-130, the immigrant does not have any legal right to remain in the United States until their approval for a green card.

With vastly expanded immigration enforcement under the Trump Administration, however, there have been reports of immigrant arrests following upon the filing or approval of an I-130 petition. This can be especially problematic if you have any record of arrests or other issues that might make you deportable.

Get Advice From an Immigration Lawyer

If you are an undocumented immigrant who wishes to obtain a green card based on marriage, you should absolutely consult with an immigration attorney before making any decisions.

Whatever you do, don't walk into an office of USCIS to ask for advice. Such a move could end up with you getting removed (deported) from the United States quite quickly, and prohibited from returning for many years. An attorney can help you evaluate your situation, determine whether you have a possible path to a green card an what risks you might face, assess your prospects of getting a waiver if you choose to go forward with an application that requires your being interviewed at a consulate abroad, and help you with the entire application process.
