For a US citizen, the path to bringing a brother or sister to America permanently runs through the family-based fourth preference (F4) category. Unlike immediate relative categories, F4 is subject to an annual quota, requiring a long priority date wait. The guide covers the steps of the sibling visa process, the realistic wait time, the priority date logic, and the 2026 costs. Yellow Law Group, headquartered in Plano (Texas) with offices in Chicago (Illinois), Irvine (California), Alpharetta (Georgia), and Fairfield (New Jersey), guides families through sibling petitions with more than 10 years of experience.
What Is the F4 Sibling Visa and Who Can Apply?
F4 is the family-based fourth preference category in which a US citizen at least 21 years old sponsors a brother or sister. Only US citizens can file the petition; Green Card (permanent resident) holders cannot sponsor a sibling. Because F4 is subject to an annual quota, the petition has a priority date queue, and a visa number becomes available only when the applicant's turn arrives. You can review the official definition on the USCIS family preference page.
The Process Step by Step: From I-130 to the Green Card
The sibling Green Card process consists of three main stages, each with its own timeline:
- I-130 petition: The US citizen files Form I-130 (Petition for Alien Relative) for the sibling. This step locks the priority date. You can find the official requirements on the USCIS I-130 page.
- Priority date wait: After the petition is approved, you wait until the cut-off date in the Visa Bulletin reaches your priority date. In F4, this wait is long.
- Consular processing or Adjustment of Status: When the priority date is current, the Green Card is obtained through consular processing (DS-260) if the sibling is abroad, or Adjustment of Status (I-485) if they are lawfully present in the US.
We cover how F4 compares with other Green Card paths in our green card decision matrix.
Wait Time: Why 15-20 Years?
The annual number of visas allocated to the F4 category is far below worldwide demand; as a result, the priority date queue takes years, even more than a decade. As of 2026, the estimated wait times by country of birth are as follows:
| Country of Birth | Estimated F4 Wait (2026) |
|---|---|
| Turkey (Rest of World) | 16 years |
| India | 17 years |
| China | 16 years |
| Philippines | 22 years |
| Mexico | 24 years |
Most of this time is spent in the priority date queue, not waiting for petition approval. I-130 approval can take 14-18 months, but waiting for a visa number to become available takes years. You can track current cut-off dates on the Department of State Visa Bulletin.
The Priority Date Lock: Why File Right Now?
The priority date is locked on the day the I-130 petition reaches USCIS and fixes your place in the green card queue. When the cut-off date in the Visa Bulletin reaches your priority date, a visa number becomes available. Every year of delay in filing pushes the Green Card a year further out. A priority date, once locked, is preserved, and the sponsor and sibling keep advancing in the queue. The most critical decision in F4 is to file the petition the moment eligibility exists, meaning as soon as the sponsor becomes a US citizen.
Spouse and Children: The Nuclear Family Comes Together
When the F4 petition is approved and the priority date becomes current, your sibling's spouse and unmarried children under 21 can receive a Green Card under the same petition as derivatives of the main petition; no separate I-130 is required. During the long wait, children turning 21 (aging out) can affect the process; the Child Status Protection Act provides protection by freezing their age in some cases.

F4 Costs and Yellow Law Group
As of 2026, the Form I-130 government filing fee is $675 ($625 if filed online). After the priority date becomes current, the consular visa fee, the Affidavit of Support (Form I-864) processing fee, and medical exam costs apply; these are paid years after filing. In F4, the real cost is not money but time, which is why early filing is the most valuable investment.
