Conditional Green Card Law and Legal Definition

A conditional green card is a green card which is issued for a two year period, and is contingent upon the immigrant meeting a specific condition. It is also known as conditional form I-551. For example, green cards which are granted based on marriage to a U.S. citizen, where the marriage has been in place for less than two years are conditional green cards. Foreign spouses may apply for a green card after the completion of the two year period.
