U.S. immigration law allows for the immigration of foreigners to the United States based on some family relationships to a U.S. citizen or legal permanent resident. If you can meet the requirements, this is one of the most practical ways to obtain a green card.
Family-based immigration falls under two basic categories: unlimited and limited.
- UNLIMITED FAMILY-BASED
Immediate Relatives of U.S. Citizens (IR): The spouse, widow(er) and unmarried children under 21 of a U.S. citizen, and the parent of a U.S. citizen who is 21 or older.
- LIMITED FAMILY-BASED
Family First Preference (F1): Unmarried sons and daughters of U.S. citizens, and their children, if any. (23,400)
Family Second Preference (F2): Spouses, minor children, and unmarried sons and daughters (over age 20) of lawful permanent residents. (114,200) At least seventy-seven percent of all visas available for this category will go to the spouses and children; the remainder will be allocated to unmarried sons and daughters.
Family Third Preference (F3): Married sons and daughters of U.S. citizens, and their spouses and children. (23,400)
Family Fourth Preference (F4): Brothers and sisters of United States citizens, and their spouses and children, provided the U.S. citizens are at least 21 years of age. (65,000)
