F4 Visa Guide 2026: Green Cards for Siblings of US Citizens

What the F4 Category Is

Section 203(a)(4) of the Immigration and Nationality Act allots 65,000 visas annually plus spillover from the first three family preferences to brothers and sisters of adult US citizens — the largest family-preference allocation and still the slowest line, because sibling demand dwarfs every other family relationship worldwide. The arithmetic is unforgiving: each approved sibling typically brings a spouse and one or two children, so a single I-130 ultimately consumes three to four visa numbers, and per-country caps throttle high-demand countries (Mexico, the Philippines, India) into multi-decade queues while the worldwide line itself runs 15 years.

F4's policy role is family unity at its broadest — and its narrowest gate is the petitioner. A 20-year-old citizen cannot file for anyone until turning 21; a 40-year resident who never naturalized cannot file at all; and no derivative petitioner chain exists (a sibling cannot "pass" the petition to their own children). Because the wait spans teenage years into middle age for derivatives, F4 practice is dominated by three disciplines: filing the instant the petitioner turns 21 (every month of delay is a month added to a 15-year queue), CSPA accounting for every derivative child, and file hygiene across decades — addresses, marriages, births, deaths, and petitioner status kept current with NVC through moves, divorces, and even the petitioner's own mortality planning.

Who Can Petition and Who Qualifies

The petitioner must be a US citizen at least 21 years old, proven by passport, naturalization certificate, or birth records plus a photo ID establishing age. The sibling relationship is proven by birth certificates showing at least one common parent; half-siblings qualify through either shared parent, with paternal half-sibling cases sometimes needing legitimation evidence depending on the father's country and the child's birth circumstances. Adoptive siblings qualify where the adoption meets INA 101(b)(1)(E) (adoption before age 16 with two years of custody and residence); step-siblings qualify where the marriage creating the step-relationship occurred before either child turned 18. Each sibling needs a separate I-130 — a citizen with two brothers abroad files twice and holds two priority dates.

The beneficiary sibling faces almost no personal bars: any age, any marital status, any country of birth (chargeability follows birth country, which sets the waiting line). What matters is admissibility at the far end — criminal history, prior immigration violations, fraud, health grounds — which should be screened at filing, not discovered at the interview 15 years later when equities have calcified. Petitioners should also confirm their own capacity to execute the I-864 eventually: the income test applies at NVC stage, and a decade-plus wait changes earnings, so lining up a potential joint sponsor early is cheap insurance. Residents who want this route must naturalize first — five years of residence (three if married to a US citizen), plus physical-presence and good-moral-character requirements — and the naturalization clock runs on top of the F4 queue, never inside it.

October 2026 Priority Dates and Wait Times

October 2026 brought F4's most meaningful movement in months, concentrated in India and the Philippines, while the worldwide line held September's surge gains.

Translate to waits: worldwide filers today face roughly 15 years; Indians roughly 20; Filipinos roughly 17; Mexicans roughly 25. The Philippines' near-nine-month final-action jump and full-year filing-date jump make it October's family bright spot, while Mexico's two-week crawl underscores the per-country trap. Because USCIS designated Dates for Filing for all October 2026 family adjustment cases, lawfully present beneficiaries with dates before November 1, 2011 (worldwide) may file I-485 now. Cross-chargeability — charging a derivative spouse's birth country instead of the principal's — can rescue families where one spouse was born in a faster country; raise it with counsel before assuming the slower line.

The I-130 to NVC to Interview Pipeline

An F4 file lives longer than most mortgages. Design every step for a 15-to-25-year lifespan.

• Step 1 — File Form I-130 with USCIS. The citizen files online ($625) or on paper ($675) per sibling, with citizenship proof, age proof, and sibling-relationship evidence. Approval (roughly a year) locks the priority date permanently — the most valuable date-stamp in family immigration. It grants no status to anyone.
• Step 2 — NVC intake when the date nears. Years later, NVC activates the case: $325 per applicant plus the $120 affidavit of support fee, then the I-864 with current tax records and civil documents for the sibling and every derivative — passports, birth/marriage certificates, police certificates, photos. Track intake on our NVC processing time page.
• Step 3 — Decades of file maintenance. Between approval and current-ness, report every birth, marriage, divorce, death, and address change; add newborn derivatives; run CSPA math as teenagers approach 21; and keep the petitioner's circumstances NVC-visible. Cases die in this phase through neglect, not law.
• Step 4 — Interviews and admission. Panel-physician medicals, consular interviews per family member (or I-485 adjustment if eligible when the filing window opens), immigrant-fee payment, travel before visa expiry, green cards by mail. Coordinate with visa application tracking and the fee calculator.

The I-864 in F4 cases routinely needs a joint sponsor: petitioners who filed at 21 are often early-career when the number arrives 15 years later with a sibling family of four attached to the household-size math. Prepare the sponsor bench — a US-domiciled spouse, relative, or friend meeting the 125-percent threshold — in the final year, not at the interview window.

F4 Costs and Fees in 2026

Core government fees for a sibling plus spouse plus two children: one $625/$675 I-130, four $325 visa fees ($1,300), one $120 support review — roughly $2,050 before incidentals, all spread across a decade and a half. Adjustment-side families substitute per-person I-485 fees at the end. Incidentals compound with time: four medicals ($800–$2,000 abroad), vaccinations, translations, adult police certificates from every country of residence since age 16, passport renewals for a family across 15+ years, and interview travel.

Decade-scale cost control: centralize every receipt from day one (NVC will not credit lost payments gladly); re-verify both USCIS and DOS schedules before each payment wave, since the April 2024 USCIS reset and periodic DOS adjustments move figures independently; and budget the derivatives' protection steps — timely DS-260 filings inside CSPA windows — as zero-cost, maximum-value actions. As with every family line, no premium processing exists and no one can sell a faster bulletin date.

CSPA Across a 15-to-25-Year Wait

F4 is CSPA's ultimate stress test: children born after filing, toddlers at filing, teenagers at filing — all converge on 21 during the queue. The formula never changes: CSPA age = biological age when the visa number becomes available minus I-130 pending days, with protection below 21 conditioned on seeking residence within one year of availability. With 15-year waits, the pending-time subtraction (often 300–500 days) rescues children up to roughly a year past their 21st birthdays — and no one older.

Worked example: I-130 pending 420 days; visa number available when the nephew is 21 years and 350 days old. CSPA age: 21 years 350 days minus 420 days = 20 years and 295 days — protected, if his DS-260 is submitted within the one-year window. Families with three-plus derivatives should build a per-child CSPA ledger in the final three years, updated at each bulletin: birth dates, projected availability, pending-day credits, and deadline dates. Two further traps: a derivative who marries before admission ages out of eligibility instantly regardless of CSPA age, and the one-year clock starts at visa availability on the final-action chart — not at NVC's first letter, which can arrive months later.

Marriage, Divorce, Birth and Death

F4's family-event rules are the most forgiving in the system — for the principal. The sibling beneficiary may marry, divorce, remarry, or stay single at any point with zero effect on the petition: eligibility turns on siblinghood, not marital status. Derivative positions shift around that fixed point: a new spouse joins as a derivative (report the marriage with the certificate); a divorce removes the former spouse; each derivative child's marriage ends that child's slot; newborns and qualifying adoptees are added with birth/adoption certificates.

Death requires counsel, not surrender. If the petitioner dies, INA 204(l) lets the beneficiary pursue the case from within or outside the US where at least one beneficiary or derivative resides in America and a substitute sponsor executes the I-864 — or USCIS may grant humanitarian reinstatement of a revoked petition on a discretionary showing. If the beneficiary dies, derivatives generally cannot continue on the petition alone, though surviving family members may have independent options worth screening. Report every vital event to the holding agency within weeks, with certificates: the file must mirror the family at all times, because interviews test the paper against the people.

F4 vs F3

Portfolio logic for citizen families: file every available category at once — F3 for each married child, F4 for each sibling, F1-equivalents where relationships qualify — because priority dates cost one filing fee to hold and a decade to replace. Use whichever matures first, keep CSPA ledgers for every derivative on every line, and remember that per-country quirks (the Philippines' F3-behind-F4 inversion, Mexico's twin 2001 walls) reward country-specific sequencing advice.
