1. What Is Family-Based Immigration?
Family-based immigration is a pathway that allows U.S. citizens and green card holders to bring qualifying relatives to live in the United States. It’s the most common route for legal immigration and accounts for nearly 65% of all new lawful permanent residents each year.
2. Who Can You Sponsor?
If you’re a U.S. Citizen, you can petition for:
- Spouse
- Children (unmarried and under 21)
- Sons/daughters (married or over 21)
- Parents (if you’re over 21)
- Siblings (if you’re over 21)
If you’re a Green Card Holder, you can sponsor:
- Spouse
- Unmarried children (under or over 21)
3. Immediate Relatives vs. Family Preference Categories
Immediate Relatives (no annual cap):
- Spouse, unmarried children under 21, and parents of U.S. citizens
Family Preference Categories (subject to yearly limits):
- F1: Unmarried sons/daughters of U.S. citizens
- F2A: Spouses and children of green card holders
- F2B: Unmarried sons/daughters of green card holders
- F3: Married sons/daughters of U.S. citizens
- F4: Siblings of U.S. citizens
Visa availability in preference categories depends on the Visa Bulletin, published monthly by the U.S. Department of State.
4. Step-by-Step Process for Sponsoring a Family Member
Step 1: File Form I-130 (Petition for Alien Relative)
- Filed with U.S. Citizenship and Immigration Services (USCIS)
- Establishes the qualifying relationship

Step 2: Wait for Approval and Priority Date to Become Current
- Immediate relatives proceed quickly
- Family preference applicants must wait for visa availability
- Check monthly: https://travel.state.gov/content/travel/en/legal/visa-law0/visa-bulletin.html
Step 3: Adjustment of Status or Consular Processing
- If inside the U.S.: File Form I-485 (Adjustment of Status)
- If outside the U.S.: Complete DS-260 through a U.S. embassy (Consular Processing)
Step 4: Biometrics, Interview & Approval
- Attend required appointments and submit evidence
- USCIS or consular officer will review eligibility and finalize the green card
5. Key Forms and Documents Required

- Form I-864 (Affidavit of Support)
- Form I-765 (optional work authorization)

6. How Long Does It Take?

Family preference: Varies by category and country; can range from 2 to 20+ years
Processing speed depends on:
- USCIS backlog

7. Common Mistakes to Avoid
