Understanding Family-Based Immigration Categories

The U.S. government divides family-based immigration into two main categories:

Immediate Relatives of U.S. Citizens

Immediate relatives receive priority in the immigration system with no annual caps on visa numbers:

Family Preference Categories

These categories have annual numerical limitations and often involve longer wait times:

  • First Preference (F1): Unmarried adult children (21 or older) of U.S. citizens.
  • Second Preference (F2):
    • F2A: Spouses and unmarried children (under 21) of permanent residents
    • F2B: Unmarried adult children (21 or older) of permanent residents.
  • Third Preference (F3): Married children of U.S. citizens, regardless of age.
  • Fourth Preference (F4): Siblings of U.S. citizens, provided the U.S. citizen is at least 21 years old.

The Family-Based Immigration Process

  • File the Petition
    • The U.S. citizen or permanent resident family member (the petitioner) must file Form I-130 (“Petition for Alien Relative”), with USCIS.
  • Wait for USCIS Approval
    • After filing, USCIS will review your petition. Processing times vary based on the family relationship and USCIS workload.
  • Visa Availability
    • Immediate relatives can proceed immediately after petition approval. Family preference categories must wait until a visa becomes available according to the Visa Bulletin.
  • Apply for a Green Card
    • Depending on where the beneficiary lives, they will apply via one of the following processes:
  • Attend the Interview
  • Receive Your Green Card
    • If approved, you’ll receive your green card and begin your life as a permanent resident in the United States.
