Which Family Members Can Be Sponsored? Immediate Relatives vs. Preference Categories
U.S. immigration law creates two distinct tiers of family-based sponsorship. Understanding which tier applies to your relative determines how long they will wait and what visa numbers they need.
Immediate Relatives of U.S. Citizens (No Annual Cap)
Under INA § 201(b)(2)(A)(i), the following relatives of U.S. citizens are classified as immediate relatives and are not subject to annual numerical limits — meaning a visa is available as soon as USCIS approves the petition:
- Spouses of U.S. citizens
- Unmarried children under 21 of U.S. citizens
- Parents of U.S. citizens (petitioner must be at least 21 years old)
Because there is no visa backlog for immediate relatives, processing time is determined almost entirely by USCIS processing times and, if applicable, consular appointment availability — not a waiting list.
Preference Category Relatives (Subject to Annual Caps)
All other qualifying relatives fall into numbered preference categories under INA § 203(a). Congress sets annual limits on how many visas each category can issue, which creates backlogs — sometimes lasting many years — especially for nationals of high-demand countries like Mexico, Philippines, India, and China. According to USCIS, the family preference categories are:
- F1: Unmarried sons and daughters (age 21+) of U.S. citizens
- F2A: Spouses and unmarried children (under 21) of LPRs
- F2B: Unmarried sons and daughters (age 21+) of LPRs
- F3: Married sons and daughters of U.S. citizens
- F4: Brothers and sisters of adult U.S. citizens (petitioner must be 21+)
Notably, U.S. LPRs cannot sponsor parents, siblings, or married children — only U.S. citizens can do so. If you are a green card holder, naturalizing to citizenship opens significantly more sponsorship options.
Visa Backlogs and Priority Dates: Why Country of Birth Changes Everything
For preference category relatives, the date USCIS receives the initial petition (Form I-130) becomes the applicant's priority date. A visa becomes available only when the monthly State Department Visa Bulletin shows that priority date is current for the applicant's category and country of birth.
Country of birth — not citizenship — controls which per-country quota applies. Because INA § 202(a)(2) limits any single country to no more than 7% of the total annual family-preference visas, nationals of high-emigration countries like Mexico, the Philippines, India, and China face dramatically longer waits than nationals of low-demand countries in the same category.
In recent Visa Bulletins, the F4 category (siblings of U.S. citizens) has shown wait times exceeding 20 years for nationals of Mexico and the Philippines. The F2B category for Mexican nationals has historically carried waits of more than a decade. These are current lived realities for millions of applicants.
You can track current priority dates through the State Department Visa Bulletin, published monthly at travel.state.gov. USCIS also publishes a separate chart of which dates it will accept for filing adjustment of status applications — Chart A and Chart B are not always the same, and filing under the wrong chart can result in rejection.
If the applicant is outside the U.S., they wait abroad. If they entered the U.S. lawfully and remain in valid status, they may be eligible to adjust status once a visa becomes available. However, if a person entered without inspection or has accrued unlawful presence, additional bars under INA § 212(a)(9) may apply. You can find qualified help through the USCIS legal services finder.
The Affidavit of Support: What the Sponsor Is Legally Required to Do
Under INA § 213A (8 U.S.C. § 1183a), every family-based immigrant must have a sponsor who signs Form I-864, Affidavit of Support, agreeing to financially support the immigrant at a minimum of 125% of the Federal Poverty Guidelines for their household size.
This is not a formality — it is a legally enforceable contract. By signing Form I-864, the petitioner agrees:
- To support the immigrant at 125% of the federal poverty level (100% for active-duty military sponsors)
- That the obligation continues until the immigrant becomes a U.S. citizen, has worked 40 qualifying quarters under Social Security, dies, permanently leaves the U.S., or loses LPR status
- That if the immigrant uses means-tested public benefits, the federal or state agency can sue the sponsor to recover the cost
The sponsor must demonstrate income through tax returns (typically the most recent three years), W-2s, pay stubs, or employment letters. If the petitioner's income is insufficient, a joint sponsor who meets the income threshold can co-sign a separate Form I-864 — they do not need to be related to either party.
Assets can supplement income shortfalls in some cases, but liquid assets are evaluated at a ratio of 3:1 to the income gap (or 1:1 for U.S. citizens sponsoring spouses or minor children).
The petitioner cannot simply withdraw the affidavit after the immigrant arrives. Courts have ruled that the I-864 obligation is enforceable by the sponsored immigrant themselves — meaning a divorce does not end the obligation. Check the USCIS forms and filing fees page for current form requirements.
How to File: Forms, Steps, and What to Expect
Family-based green card cases follow two main pathways: adjustment of status (the applicant is already inside the U.S.) or consular processing (the applicant is abroad). Both begin with a petition to establish the qualifying relationship.
Form I-130 (Petition for Alien Relative)
The U.S. citizen or LPR petitioner files Form I-130 with USCIS to establish the family relationship. Required evidence includes proof of the petitioner's U.S. citizenship or LPR status and proof of the qualifying relationship (birth certificate, marriage certificate, adoption decree, etc.). Always verify current fees on the USCIS filing fees page before submitting.
Adjustment of Status or Consular Processing
If the immigrant is in the U.S. and eligible, they file Form I-485 (Application to Register Permanent Residence) along with Form I-864, Form I-693 (medical exam by a USCIS-designated civil surgeon), and supporting documents. If abroad, the case transfers to the National Visa Center and then a U.S. embassy or consulate.
Biometrics and Interview
Most applicants attend a biometrics appointment at a USCIS Application Support Center. An in-person interview is typically required for spousal petitions and most family-based adjustment cases. You can track your case at any time through the USCIS case status portal.
Special Situations: Divorce, Death of Petitioner, Aging Out, and Conditional Green Cards
Several life events can significantly affect a pending or approved family-based petition.
Conditional Green Cards: When a marriage is less than two years old at the time the immigrant becomes an LPR, USCIS grants a 2-year conditional green card under INA § 216. The couple must file Form I-751 jointly within the 90-day window before the card expires. If divorce has occurred, a waiver of the joint filing requirement is available based on good faith marriage, domestic abuse, or extreme hardship.
Death of the Petitioner: Under INA § 204(l), a surviving relative may request humanitarian reinstatement if they were residing in the U.S. at the time of the petitioner's death and have a qualifying substitute sponsor who signs a new Form I-864.
Aging Out — Child Status Protection Act: A child who turns 21 while a petition is pending would normally age out of their category. The Child Status Protection Act (CSPA), 8 U.S.C. § 1153(h), provides a formula to calculate an adjusted age. The child's CSPA age equals their biological age minus the number of days the I-130 was pending with USCIS.
All of these situations carry real legal risk if handled incorrectly. Use the DOJ roster of BIA-accredited representatives to find qualified low-cost or free immigration help.
| Category | Who Qualifies | Petitioner Must Be | Annual Cap (approx.) | Typical Backlog |
|---|---|---|---|---|
| Immediate Relative | Spouse, unmarried child under 21, parent | U.S. Citizen (21+ to sponsor parent) | No cap | No backlog — visa immediately available |
| F1 | Unmarried sons/daughters 21+ of U.S. citizens | U.S. Citizen | ~23,400/yr | Many years for high-demand countries |
| F2A | Spouses and unmarried children under 21 of LPRs | LPR | ~87,900/yr | Shorter than other preference categories |
| F2B | Unmarried sons/daughters 21+ of LPRs | LPR | ~26,300/yr | Many years for Mexico and Philippines |
| F3 | Married sons and daughters of U.S. citizens | U.S. Citizen | ~23,400/yr | 10-20+ years for high-demand countries |
| F4 | Brothers and sisters of U.S. citizens | U.S. Citizen (must be 21+) | ~65,000/yr | 20+ years for Philippines and Mexico |
Step-by-Step Process
- 1
Determine Eligibility and Category
Confirm that your family relationship qualifies under INA § 1153 — identify whether you are sponsoring an immediate relative (no wait) or a preference category relative (subject to annual caps and backlogs). Confirm your own status: U.S. citizens can sponsor more categories than LPRs.
- 2
File Form I-130 with USCIS
Complete and submit Form I-130 with proof of your U.S. citizenship or LPR status, proof of the qualifying family relationship (birth certificates, marriage certificate, etc.), and the applicable filing fee. Verify the current fee on the USCIS filing fees page before submitting — fees change and submitting with incorrect payment causes rejection.
- 3
Monitor Visa Bulletin and Priority Date
For preference category relatives, track the monthly State Department Visa Bulletin. Your relative cannot move forward until their priority date is listed as current in Chart A or Chart B for their category and country of birth. The priority date is set on the date USCIS receives your I-130.
- 4
Prepare and File Form I-864 Affidavit of Support
Gather your most recent 3 years of federal tax returns, current pay stubs, and an employment verification letter. Complete Form I-864 and confirm your income meets 125% of the Federal Poverty Guidelines for your household size. If your income is insufficient, identify a joint sponsor who meets the threshold independently.
- 5
File for Adjustment of Status or Begin Consular Processing
If the immigrant is in the U.S. in lawful status and a visa is available, file Form I-485 along with Form I-864, Form I-693 (medical exam by a USCIS-designated civil surgeon), and supporting documents. If the immigrant is abroad, USCIS transfers the approved I-130 to the National Visa Center, which schedules a consular interview at the relevant U.S. embassy or consulate.
- 6
Attend Biometrics Appointment and Interview
USCIS will schedule a biometrics appointment at an Application Support Center. Most family-based applicants — especially spouses — are called for an in-person interview at a USCIS field office or U.S. consulate. Bring all original documents and any requested evidence. After approval, the green card is mailed to the applicant. Track the case through the USCIS case status portal.

Frequently Asked Questions
No. Under INA § 1153(a), only U.S. citizens can sponsor parents for a green card — lawful permanent residents cannot. If you are an LPR and want to sponsor your parents, you must first naturalize to U.S. citizenship. Once naturalized, you can file Form I-130 for your parents as immediate relatives, meaning no annual cap and no visa backlog applies.
It depends entirely on the relationship and country of birth. Immediate relatives of U.S. citizens face no visa backlog — their wait is determined by USCIS processing times, which you can check at the USCIS processing times page. Preference category relatives can wait anywhere from two years to 20+ years depending on category and country of birth. Always verify current wait times through the monthly State Department Visa Bulletin.
Under INA § 204(l) (8 U.S.C. § 1154(l)), an approved petition is not automatically revoked upon the petitioner's death if the beneficiary was residing in the U.S. at the time of death and a qualifying substitute sponsor signs a new Form I-864. USCIS may exercise discretion to approve the case on humanitarian grounds. If the death occurs before I-130 approval, a survivor petition may still be available — consult a qualified immigration attorney or accredited representative.
Yes, but only if you are a U.S. citizen and at least 21 years old — lawful permanent residents cannot sponsor siblings. Siblings fall under the F4 preference category under INA § 1153(a)(4), which carries an annual cap and backlogs of 20+ years for nationals of Mexico and the Philippines. File Form I-130 as early as possible since the priority date is set on the date USCIS receives the petition.
Yes. Under INA § 213A, the sponsoring petitioner must demonstrate income of at least 125% of the Federal Poverty Guidelines for their household size, which includes the immigrant being sponsored. If your income falls short, a joint sponsor can co-sign a separate Form I-864. The joint sponsor does not need to be a family member but must independently meet the income threshold and accepts the same legal obligations as the primary sponsor.
Adjustment of status (Form I-485) is available when the immigrant is already inside the U.S. in lawful status and a visa is immediately available — they complete the entire process without leaving the country. Consular processing is used when the immigrant is abroad; the approved I-130 is sent to the National Visa Center and then a U.S. consulate, where the immigrant attends an in-person interview and receives an immigrant visa to enter the U.S. as a lawful permanent resident. Both pathways require Form I-864 and a medical examination.
