F4 Green Card for Siblings: Process, Wait Times, and Costs

The F4 green card for siblings lets a U.S. citizen sponsor a brother or sister for permanent residence, but the category is capped at roughly 65,000 visas a year and the wait now runs 17 to 25 years depending on the sibling’s country of birth.¹ The legal path is real. The timeline is measured in decades, not years, and that shapes every decision that follows.

Who Can Sponsor a Sibling

Only a U.S. citizen who is at least 21 years old can file for a sibling under F4.² Green card holders cannot sponsor siblings through this or any other category. Permanent residents who file anyway lose the filing fee and months of time when USCIS denies the petition.

The definition of “sibling” reaches beyond full biological brothers and sisters. Half-siblings qualify as long as they share at least one biological parent.³ Step-siblings qualify if the marriage that created the step-relationship happened before the younger of the two children turned 18.⁴ Adopted siblings qualify if the adoption was finalized before the adopted child turned 16, with a narrow exception allowing a biological sibling of an already-adopted child to qualify if the same parents adopt them before age 18.⁵

These age thresholds are rigid. A step-parent marriage dated the day after an 18th birthday does not qualify the step-sibling. Consular officers scrutinize these dates during adjudication, and the documentation has to come from government records or certified legal documents.

Filing the I-130 Petition

The process starts when the citizen files Form I-130, Petition for Alien Relative, with USCIS.⁶ The I-130 is not the green card application. It asks the government to recognize the sibling relationship and place the beneficiary in line. The date USCIS receives the petition becomes the priority date, which sets the sibling’s place in the queue.

Required documentation includes:

Proof of the petitioner’s U.S. citizenship, such as a passport, naturalization certificate, or U.S. birth certificate.
Proof of the sibling relationship: birth certificates showing at least one shared parent. Step-siblings also need the relevant marriage certificate and proof that any prior marriages ended. Adopted siblings need the adoption decree.⁴
Certified English translations of any document not already in English.

Names, dates of birth, and places of birth must match across every document filed. Small discrepancies routinely trigger Requests for Evidence that add months. If a document contains an error, get it corrected at the issuing authority before you file.

The I-130 can be submitted online or on paper through a USCIS lockbox. Fees differ between the two methods and change periodically, so check the current schedule on the USCIS site before sending anything in.

How Long the Wait Actually Is

F4 has the longest wait of any family-sponsored preference. Federal law caps the category at 65,000 visas a year (plus any unused visas rolling down from higher family preferences), and a separate rule limits any single country to no more than 7 percent of family and employment visas issued in a given year.⁷ The per-country cap is why applicants from a few high-demand countries wait far longer than everyone else.

The June 2026 Visa Bulletin’s Final Action Dates translate into these approximate waits from the date the I-130 was filed:

Most countries: about 17 to 18 years (petitions filed November 2008 now current)
India: about 20 years (November 2006)
Philippines: about 19 years (July 2007)
Mexico: about 25 years (April 2001)
China (mainland-born): about 17 to 18 years (November 2008)

A petition filed today for a sibling born in Mexico will likely not result in a visa until the 2050s. These figures are the reality of the category, not projections that improve with better paperwork.

Reading the Visa Bulletin

Each month the Department of State publishes two charts. Final Action Dates show which priority dates can actually be issued visas. Dates for Filing show when the National Visa Center will start collecting final paperwork ahead of visa availability. When your priority date falls earlier than the date listed for your category and country, your date is “current” and the case can move forward.

Priority dates do not advance predictably. Some months they jump several weeks, other months they stall or retrogress. Checking the bulletin monthly is the only reliable way to know where a case stands.

Costs and the Affidavit of Support

Fees show up at several stages and go to different agencies. Beyond the I-130 filing fee to USCIS, the National Visa Center charges $325 per person for immigrant visa processing and $120 for Affidavit of Support review.⁹ Add the medical examination (typically $250 to $430 depending on provider and location) and the USCIS immigrant fee collected after visa approval, and government fees alone run well into four figures per person. Attorney fees for a straightforward case start around $2,500.

Before a visa can be issued, the petitioner files Form I-864, Affidavit of Support. This is a legally enforceable contract with the federal government to maintain the sibling’s income at 125 percent of the Federal Poverty Guidelines for the combined household size.¹⁰ The obligation runs until the sibling naturalizes, works 40 qualifying quarters under Social Security, permanently leaves the country, or dies.

For 2026, the minimum income thresholds for sponsors in the 48 contiguous states are $27,050 for a household of two, $34,150 for three, and $41,250 for four. Alaska and Hawaii use higher thresholds.¹¹ Your household count includes yourself, your dependents, anyone else you’ve sponsored who hasn’t aged off the obligation, and the sibling plus any derivative family members you are sponsoring now.

If your income is short, a joint sponsor can sign a separate I-864 and take on the same obligation. The joint sponsor must be a U.S. citizen or green card holder, at least 18, and domiciled in the United States. If the sibling later receives certain means-tested benefits, the agency that provided them can sue either sponsor for reimbursement.

From Approved Petition to Green Card

After USCIS approves the I-130 and a visa number finally becomes available, the case moves to the National Visa Center for collection of civil documents, fees, and the Affidavit of Support. What happens next depends on where the sibling lives.

Consular Processing Abroad

Siblings living outside the United States go through consular processing. The NVC schedules an interview at the U.S. embassy or consulate in the beneficiary’s home country. Before the interview, the sibling completes a medical exam with an embassy-approved physician, which checks for communicable diseases and confirms required vaccinations.

At the interview, a consular officer reviews the documents, confirms the relationship, and runs security and background checks. If everything clears, the sibling receives an immigrant visa packet and uses it at a U.S. port of entry, where they are admitted as a permanent resident.¹²

Adjustment of Status Inside the U.S.

A sibling already physically present in the United States after a lawful admission or parole may file Form I-485 for adjustment of status instead of traveling abroad. The visa has to be immediately available both when the I-485 is filed and when USCIS decides it, and the applicant has to be admissible and free of any bars on adjustment.¹³ Some people who entered without inspection or overstayed a visa may still adjust under INA 245(i), but that provision has strict cutoffs and applies only to those covered by petitions filed by specific statutory deadlines.¹²

Spouses and Children of the Sibling

The F4 category also covers the sibling’s spouse and unmarried children under 21, who receive derivative status under the same visa without a separate I-130.⁴ They can accompany or follow to join the principal beneficiary under INA 203(d).¹

Because the wait routinely exceeds 17 years, children who were toddlers at filing may be well past 21 by the time a visa becomes available. The Child Status Protection Act adjusts a child’s age for eligibility purposes: take the child’s biological age when the visa becomes available, then subtract the number of days the I-130 was pending before USCIS approved it. The result is the CSPA age.¹⁴ A child biologically 23 when the visa opens, from a petition that sat 3 years at USCIS, has a CSPA age of 20 and stays eligible. The child must also seek to acquire the visa within one year of it becoming available. CSPA does not rescue every case, especially when the I-130 was approved quickly but the visa backlog itself lasted decades.

What Can Still Derail the Case

An approved petition and a current priority date are not the end of the analysis. A sibling can still be denied at the visa stage on grounds of inadmissibility: certain criminal convictions, communicable diseases, prior immigration violations such as an overstay or entry without inspection, fraud or misrepresentation on a prior application, and security concerns.¹² Form I-601 requests a waiver of many of these grounds; Form I-212 requests permission to reapply after a prior removal. Waivers turn on discretion, so strong documentation matters but never guarantees approval.

If the U.S. Citizen Petitioner Dies

Over a 20-year wait, the petitioner’s death is a real possibility. An approved I-130 is automatically revoked when the petitioner dies, but USCIS can reinstate the approval as a matter of humanitarian discretion if the beneficiary requests it and shows that a substitute sponsor is willing and able to file the Affidavit of Support.¹⁵ A separate protection under INA 204(l) applies when the beneficiary was residing in the United States when the petitioner died; USCIS may still approve the case if the beneficiary continues to reside here and meets all other requirements.¹⁶

Keeping the Green Card After Arrival

Receiving the green card starts a new set of obligations. The most common way F4 immigrants lose status is extended travel. A trip abroad of more than one year generally raises a presumption of abandonment, and even absences of six months or longer draw scrutiny at the border and can break the continuous residence required for naturalization later.¹⁷

If a longer absence is unavoidable, apply for a re-entry permit on Form I-131 before leaving. The permit lasts up to two years and lets you return without a returning resident visa from a consulate. It does not preserve continuous residence for naturalization purposes. After a wait that may have taken 20 years, losing status to a long trip is a preventable outcome that catches families off guard.
