Complete Guide to Family-Based Immigration
Your Path to Reuniting with Loved Ones in the United States

Family reunification remains the cornerstone of the U.S. immigration system. Every year, thousands of U.S. citizens and permanent residents file immigration petitions to bring their loved ones to live with them in the United States. This comprehensive guide by TRW Law Firm explores the ins and outs of family-based immigration, outlines eligibility requirements, breaks down the process step-by-step, and offers strategic insights into making your application stronger.
📍 Understanding Family-Based Immigration Categories
The U.S. immigration system provides two broad pathways for family-sponsored green cards:
🟩 Immediate Relatives of U.S. Citizens
Immediate relatives benefit from priority processing and no annual caps on the number of green cards issued. These relationships include:
🟩 Spouses of U.S. Citizens (IR1/CR1): If legally married to a U.S. citizen, a foreign spouse qualifies for a green card. If married for less than 2 years at the time of approval, the spouse receives a conditional green card (CR1).
🟩 Parents of U.S. Citizens (IR5): U.S. citizens who are at least 21 years old can sponsor their biological or adoptive parents.
🟩 Unmarried Children Under 21 of U.S. Citizens (IR2/CR2): Biological, step, or adopted children under 21 and unmarried are eligible for this category.
🟩 Family Preference Categories
These categories are subject to annual numerical limits and generally have longer wait times:
🟩 F1: Unmarried adult children (21+) of U.S. citizens
🟩 F2A: Spouses and unmarried minor children of green card holders
🟩 F2B: Unmarried adult children of green card holders
🟩 F3: Married children of U.S. citizens
🟩 F4: Siblings of U.S. citizens (sponsor must be 21+)
📅 To track your visa priority date, refer to the Visa Bulletin.
🔒 The Family-Based Immigration Process: Step by Step
1. Filing the Petition (Form I-130)
The first step is for the sponsoring family member (petitioner) to file Form I-130 (Petition for Alien Relative) with U.S. Citizenship and Immigration Services (USCIS). This form establishes the family relationship between the sponsor and the beneficiary.
Required documents:
- Proof of U.S. citizenship or permanent residency
- Birth or marriage certificates
- Photos
- Evidence of a genuine relationship
2. USCIS Petition Approval
USCIS processes the petition and issues either an approval (notice of action) or a Request for Evidence (RFE). Processing times vary between 6 to 24 months, depending on the category and location.
3. Visa Availability Check
If you fall under the immediate relative category, you may proceed directly to the next step. If you are under a family preference category, you must wait until your priority date becomes current, as outlined in the Visa Bulletin.
4. Green Card Application
Depending on the location of the beneficiary:
🌎 Consular Processing (Outside the U.S.): The National Visa Center (NVC) will collect documents, fees, and schedule a visa interview at the U.S. Embassy or Consulate.
🌊 Adjustment of Status (Inside the U.S.): The applicant files Form I-485 (Application to Register Permanent Residence or Adjust Status) to obtain the green card without leaving the country.
5. Attend the Green Card Interview
Interviews are conducted by USCIS (for AOS) or the consulate (for CP). Applicants must bring:
- Valid passport
- Medical examination report
- Relationship evidence
- Financial sponsorship documents (Form I-864)
6. Green Card Issuance
Upon approval, the applicant receives their green card. Spouses married for less than 2 years receive a conditional green card, valid for 2 years. They must jointly file Form I-751 to remove the conditions before expiration.
🏛️ Common Challenges in Family-Based Immigration
🛳 Proving a Bona Fide Relationship
USCIS closely scrutinizes certain categories for fraud, particularly marriage-based applications. Evidence should include:
- Joint bank accounts
- Lease agreements
- Photographs
- Chat logs and correspondence
- Affidavits from friends and family
🔜 Addressing Long Wait Times
Some categories, such as F4 (siblings) or F3 (married children), can take over a decade. Strategic planning is key, especially when children may “age out” of eligibility.
🔓 Inadmissibility Issues
Grounds of inadmissibility include prior visa overstays, unlawful presence, or criminal history. In such cases, a waiver of inadmissibility may be required by filing Form I-601.
💸 Understanding the Costs
Here is an estimated cost breakdown:
Item | Cost (USD) |
---|---|
Form I-130 filing fee | $675 |
Form I-485 filing fee | $1440 |
DS-260 (for CP) | $325 |
Medical exam | $200–$500 |
Biometrics fee | $85 |
Affidavit of Support | No separate fee |
🌟 Special Considerations
Since the repeal of DOMA, same-sex spouses are treated the same as opposite-sex spouses. USCIS does not discriminate based on sexual orientation or gender identity.
🎓 Adopted Children
Adopted children qualify under family-based immigration if:
- The adoption occurred before age 16
- The child has lived with the adoptive parents for at least 2 years
Special immigration rules apply for international adoptions under the Hague Convention.
🏡 Conditional Residency
Spouses married less than 2 years at the time of approval receive a 2-year conditional green card. Within 90 days before expiration, file Form I-751 jointly to convert to a 10-year card.
💼 Financial Requirements
Petitioners must demonstrate financial capability using Form I-864. Sponsors must have household income at least 125% of the Federal Poverty Guidelines. A joint sponsor can be added if the petitioner’s income is insufficient.
