If you hold DACA status and then marry a U.S. citizen, you may be eligible for a green card based on your marriage. You would need to meet the main eligibility requirements for getting a marriage-based green card. In other words, your marriage must be legal and made in good faith, rather than for the purpose of committing immigration fraud. You also must be able to adjust your status to a green card while staying within the U.S., which is a process available only to foreign nationals who have lawfully entered the U.S. (A foreign national also can get a green card through the consular processing system in their home country, but you should not leave the U.S. if you have DACA because you may not be able to return.) You can adjust your status only if you are not inadmissible to the U.S. Common grounds of inadmissibility include criminal convictions or unlawful presence in the U.S.
Having DACA status does not prove that you entered into your marriage in good faith or negate criminal convictions on your record. On the other hand, it may help you negate problems caused by unlawful presence in the U.S. and prove that you lawfully entered the U.S.
The DACA program no longer allows foreign nationals to get permission to travel outside the U.S., formerly known as advance parole. However, foreign nationals who previously held DACA often obtained advance parole. This means that they left the U.S. and returned there based on their travel authorization, which counts as a lawful entry. If you have married a U.S. citizen in good faith and meet the other requirements for adjustment of status, you can use that process to get a green card in the U.S. This will give you lawful permanent resident status, regardless of what happens to the DACA program.
If advance parole eventually becomes an option for DACA recipients again, a foreign national who is not eligible for adjustment of status may be able to use the consular processing procedures to get their green card. They would need to be aware that a three-year bar on reentry to the U.S. applies if they have stayed unlawfully in the U.S. for 180 days or more. A 10-year bar on reentry applies if they have stayed unlawfully in the U.S. for one year or more. Fortunately, DACA status does not count as unlawful presence, nor does any time that a foreign national spends in the U.S. while they are under 18. If you got DACA before you turned 18 or shortly afterward, you may not have enough days of unlawful presence to trigger either bar.
Foreign nationals will be permanently barred from entering the U.S. if they were unlawfully present in the U.S. for at least one year, or were previously removed from the U.S., and then they unlawfully entered or attempted to enter the U.S. again. If you have protection under the DACA program, you likely have accumulated at least one year of unlawful presence in the U.S. This is because you must have lacked legal status when the DACA program was started and must have lived in the U.S. for five years before then to be eligible for DACA.
If you have not left the U.S. since the unlawful stay that makes you eligible for DACA, you probably do not need to worry about the permanent bar. If you left and returned multiple times, the permanent bar probably will apply to you. This means that leaving the U.S. to go through consular processing in your home country may not be a valid route to an immigrant visa and green card, even if you have a valid marriage to a U.S. citizen.
