Green card marriage refers to a marriage in which a U.S. citizen marries a foreign citizen for the purpose of allowing the foreign citizen to become a permanent U.S. resident. This is one of the most common ways to become a United States permanent resident (Green Card holder). The marriage can take place in the United States or abroad. A Green Card obtained by marriage will have conditions that needs be removed within a certain amount of time. A conditional green card is issued to residents that get married to a green card holder or U.S. citizen. Once the application for a permanent green card is approved, the person can apply for U.S. citizenship and obtain a United States passport. In order to regulate these type of marriages entered into for the purpose of circumventing U.S. immigration laws, the marriage fraud amendments were enacted.
