How U.S. Citizens Can Petition for Brothers and Sisters

Can a U.S. citizen petition for a brother or sister to receive a green card? Yes. U.S. citizens who are at least 21 years old may file a family immigration petition for an eligible sibling. This is known as the F4 sibling visa or fourth family-sponsored preference category.

For families separated between the United States and the Philippines, the process offers a potential path to reunification—but it is important to understand that a sibling petition can involve a very long wait. Filing early establishes a place in the visa queue; approval of the petition does not mean the sibling can immediately immigrate.

Who Can Petition for a Brother or Sister?

To petition for your sibling, you must be a U.S. citizen age 21 or older. Lawful permanent residents (green card holders) cannot petition for brothers and sisters. If you are currently a permanent resident, you would need to become a U.S. citizen before filing in this category.

Brothers and sisters can qualify through shared parents and, in some circumstances, qualifying step- or adoptive relationships. The documents needed depend on how the family relationship was established.

For information about becoming a citizen, see our U.S. citizenship through marriage guide. Becoming a U.S. citizen through another qualifying route may also make sibling sponsorship possible.

How Does the F4 Sibling Immigration Process Work?

Step 1: Prepare and File Form I-130

The U.S. citizen petitioner files Form I-130, Petition for Alien Relative, with USCIS. You must document your own U.S. citizenship and the qualifying relationship to your brother or sister.

Common evidence includes the petitioner’s birth certificate, the sibling’s birth certificate showing at least one shared parent, and proof of U.S. citizenship. Cases involving a shared father with different mothers, adoption, or a step-relationship can require additional records.

See the official USCIS Form I-130 information and Form I-130 instructions for the applicable evidence requirements.

Step 2: Receive a Priority Date

The filing establishes a priority date, generally the date USCIS properly receives the petition. This date determines the petition’s place in line for an immigrant visa under the F4 category.

After filing, USCIS may review the petition and issue an approval, a request for evidence, or another decision. Approval establishes the qualifying relationship; it does not make an immigrant visa immediately available.

Step 3: Wait for Visa Availability

The F4 category has annual numerical limits, so petitions are subject to visa backlogs. The waiting period depends on the applicant’s country of chargeability, priority date, and movement in the U.S. Department of State’s monthly Visa Bulletin.

For applicants chargeable to the Philippines, the wait can be particularly long. As an illustration of the backlog—not a prediction of a newly filed case’s completion—the October 2026 Visa Bulletin’s F4 final-action cutoff for the Philippines is May 15, 2008. These cutoff dates can advance, remain unchanged, or move backward. Always consult the latest bulletin rather than treating a historical date as a fixed processing-time estimate.

Step 4: National Visa Center and Embassy Processing

When the case becomes eligible for the appropriate next step, the National Visa Center (NVC) provides instructions for immigrant visa processing. This generally involves the DS-260 immigrant visa application, civil records, financial sponsorship, and required fees. The applicant later follows the applicable U.S. Embassy or consulate’s medical-examination and interview instructions.

For eligible relatives in the Philippines, consular interviews are generally handled through the U.S. Embassy in Manila. Visa issuance is not guaranteed merely because USCIS approved Form I-130.

Can Your Sibling’s Spouse and Children Immigrate Too?

One advantage of the F4 category is that the principal sibling’s qualifying spouse and unmarried children may be eligible as derivative beneficiaries rather than requiring a separate I-130 petition for each person. Their eligibility must be checked carefully when the visa becomes available.

Children’s age eligibility can be affected by the Child Status Protection Act (CSPA), which has detailed calculations and procedural requirements. A child approaching 21 should not automatically be assumed ineligible—or automatically protected. Marriage can also affect a child’s derivative eligibility. Raise these issues well before the immigrant visa stage.

What Financial Sponsorship Is Required?

Financial sponsorship is generally required at the immigrant visa stage. The petitioner normally provides Form I-864, Affidavit of Support, and supporting financial evidence. Most sponsors must demonstrate the required income, generally 125% of the applicable federal poverty guidelines, unless a qualifying exception applies.

A joint sponsor or qualifying assets may be possible in some cases. Having adequate income when the I-130 is initially filed does not eliminate the need to satisfy the financial sponsorship requirements at the later visa stage. Our immigration sponsorship income requirements guide explains the general framework, though the correct Form I-864 requirements must be reviewed for the sibling case itself.

How Long Does It Take to Bring a Sibling to the United States?

Siblings do not have an immediate-relative immigrant visa category. F4 applicants must wait for a visa number to become available, which can take many years and, in heavily backlogged countries, potentially decades. USCIS petition processing time and visa-number waiting time are different parts of the process.

A current Visa Bulletin cutoff date does not tell you how long a new petition filed today will take. Because the dates move unevenly and annual visa limits apply, reliable long-range arrival dates cannot be promised.

Common Mistakes to Avoid

• Assuming a green card holder can petition for a sibling. The petitioner must be a U.S. citizen at least 21 years old.
• Confusing I-130 approval with green-card approval. F4 visa availability is a separate requirement.
• Leaving out relationship records. Birth certificates and, where necessary, additional family evidence should clearly establish the qualifying sibling relationship.
• Overlooking children and family changes. Derivative family members, marriages, deaths, and aging-out questions should be reviewed as circumstances change.
• Ignoring government notices. Keep your mailing and contact information current and respond to USCIS or NVC instructions when required.

Frequently Asked Questions About Sibling Petitions

Can I petition for my married sister or brother?

Yes. An eligible U.S. citizen can petition for a married sibling. The sibling’s qualifying spouse and children may also be eligible for derivative visas.

Can I file for more than one sibling?

Yes, but you generally file a separate Form I-130 for each eligible brother or sister and pay the applicable government filing fee for each petition.

Will my sibling be allowed to work in the United States while waiting?

An I-130 filing or approval by itself does not grant permission to live or work in the United States. Any independent visa or employment eligibility must be evaluated separately.

Can my sibling visit the United States while an F4 petition is pending?

Having a pending immigrant petition does not automatically prohibit a temporary visit, but the sibling must still qualify for the applicable visitor visa or admission and demonstrate a genuine temporary purpose under the relevant rules.
