You may be wondering, can I apply for a marriage-based green card in the US? If a person who is not a citizen or a lawful permanent resident marries a citizen, he or she has the same legal status as before. However, that person then becomes eligible to immediately seek to become a lawful permanent resident. As a permanent resident, that person will have most of the rights and privileges of a U.S. citizen, and will be eligible for naturalization after five years.
