Green Card Through a Sibling (F4 Category): Timeline & Guide (2026)

The F4 (Fourth Preference Family) category allows U.S. citizens to sponsor their brothers and sisters for green cards. It is the broadest family-based category — and the slowest. With wait times stretching 15–25 years depending on the country, the F4 process is a marathon that requires patience, planning, and vigilant case management.

Despite the long wait, tens of thousands of families use this category every year. This guide explains how it works, the realistic wait times, and what you can do during the backlog.

Eligibility

Who can petition

• U.S. citizens only — green card holders cannot sponsor siblings
• The petitioner must be at least 21 years old

Who can be sponsored

• Brothers and sisters of the U.S. citizen (full siblings or half-siblings)
• The sibling’s spouse and unmarried children under 21 are included as derivative beneficiaries

Relationship requirements

You must prove the sibling relationship through:

• Birth certificates showing at least one common parent
• Adoption decrees (if the relationship is through adoption, specific rules apply)
• Marriage certificates (if the relationship is through a stepparent)

Half-siblings (sharing one parent) qualify. Step-siblings (no biological relationship, connected only through marriage of parents) do not qualify.

The process

Step 1: File Form I-130

The U.S. citizen files Form I-130 (Petition for Alien Relative) with USCIS.

Required documents:

• Proof of U.S. citizenship (passport, naturalization certificate, birth certificate)
• Petitioner’s birth certificate
• Beneficiary’s (sibling’s) birth certificate
• Both birth certificates must show at least one common parent
• If through a father: parents’ marriage certificate and evidence the father had a legal relationship to both children (legitimation, if applicable)
• Filing fee: $625

Step 2: Wait for I-130 approval

USCIS reviews the petition and verifies the sibling relationship. Processing time: 8–14 months in 2026.

Once approved, the I-130 establishes a priority date — the date USCIS received the petition. This date is your place in line.

Step 3: Wait for priority date to become current

This is the long wait. Your priority date must appear before the Final Action Date in the monthly Visa Bulletin for your sibling’s country of chargeability (typically their country of birth).

During this period:

• The case sits at the National Visa Center (NVC) in a “waiting” status
• NVC will contact you when the date approaches currency
• You must respond to NVC requests and keep your contact information current
• Do not let the case go dormant for more than 1 year — NVC can terminate the petition under INA § 203(g)

Step 4: NVC processing and DS-260

When the priority date approaches currency, the NVC activates the case:

• Pay fees ($325 immigrant visa fee + $120 affidavit of support fee)
• Submit Form DS-260 (immigrant visa application)
• Upload civil documents
• Submit Form I-864 (Affidavit of Support)

Step 5: Embassy interview

Your sibling attends an interview at the U.S. embassy or consulate in their country. The officer verifies the relationship, reviews documents, and checks admissibility.

Step 6: Immigrant visa and entry

If approved, your sibling receives an immigrant visa stamp and enters the U.S. as a lawful permanent resident. The green card arrives by mail within 2–4 weeks of entry.

Current wait times (2026)

Based on the Final Action Dates in recent Visa Bulletins:

These waits are measured from the I-130 filing date (priority date) to when the date becomes current. If filing today, your sibling would receive their green card in the 2040s.

Annual visa allocation

The F4 category receives approximately 65,000 immigrant visas per year (plus unused visas from other family categories). With hundreds of thousands of approved petitions waiting, the backlog grows faster than visas are allocated.

What to do during the wait

Keep information current with NVC

• Respond to every NVC communication
• Update your address if you move
• Do not let the case sit without activity for 12+ months

Protect against aging out

Your sibling’s children who are under 21 at the time of I-130 filing are derivative beneficiaries. But if they turn 21 during the 15–25 year wait, they may age out — losing their eligibility as derivative beneficiaries.

Child Status Protection Act (CSPA) provides some relief:

• The child’s age is calculated as: biological age on the date a visa becomes available, minus the time the I-130 was pending
• If the CSPA-adjusted age is under 21, the child retains derivative status
• If over 21, the child ages out and would need their own petition

Example: A child is 10 when the I-130 is filed. The I-130 takes 12 months to approve. 17 years later, when the priority date becomes current, the child is 27. CSPA age: 27 − 1 (year pending) = 26. The child has aged out.

Given the extremely long F4 waits, aging out of derivative children is very common. Plan for this — the aged-out child may need an independent immigration path.

If the sibling marries or has children

• If the sibling marries during the wait, they become ineligible for F4. They would need a different visa category or the marriage must end.
• If the sibling has children during the wait, the children born after the I-130 filing date may or may not qualify as derivatives — this depends on timing and CSPA calculations.

Explore parallel immigration paths

Given the 15–25 year wait, many families explore alternative immigration categories in parallel:

• Diversity visa lottery: If the sibling’s country is eligible, they can enter the DV lottery annually
• Employment-based: The sibling may qualify for an employer-sponsored green card (EB-2, EB-3, EB-1) independently
• Other family categories: If the sibling marries a U.S. citizen, the marriage-based immediate relative path (no wait) would be faster

Costs

Attorney fees for the full process (I-130 through embassy): $2,000–$5,000.

Is the F4 category worth it?

The F4 category requires commitment to a 15–25 year process. It makes sense when:

• Your sibling has no other immigration path
• Your sibling’s children are very young (better CSPA protection)
• You want to establish a priority date now, even if your sibling explores other options in the meantime

Filing the I-130 now costs only $625 and locks in a priority date. Even if your sibling finds a faster path later, there is no harm in having the I-130 on file. Some families file the I-130 as a long-term backup while pursuing employment-based or diversity visa options in parallel.
