Family First Preference Law and Legal Definition

Family First Preference is a limited category used in family immigration in order to identify unmarried sons and daughters of U.S. citizens, and their children, if any. Family First Preference Green Cards are issued to:

1. Unmarried children (age 21 or older) who have at least one U.S. citizen parent;

2. Unmarried stepchildren (age 21 or older), if the marriage creating the stepchild relationship took place before the child's 18th birthday; and

3. U.S. citizens to sponsor the Green Card application of their unmarried foreign born children (age 21 or older).
