Our Sibling Visa (F4) Legal Service: What It Covers
A US citizen bringing a brother or sister to America permanently is possible through the family-based fourth preference (F4) category. Yellow Law Group manages your sibling Green Card process from the relative petition (I-130) to priority date tracking and the interview; correct filing, protecting the priority date, and keeping the file current through the long wait are our responsibility.
We cover the steps, the realistic wait time, and the 2026 costs in our how to get a US sibling visa guide.
What Is F4? The Sibling of a US Citizen
F4 is the family-based fourth preference visa 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. Unlike the immediate relative category, F4 is subject to an annual quota, so the petition has a priority date queue. You can review the official definition on the USCIS family preference page.
The Most Important Reality: a 15-20 Year Wait and the Priority Date
The most critical reality of the F4 category is the long wait time. As of 2026, the wait for applicants born in Turkey is generally around 16 years; for the Philippines it can reach 22 and for Mexico 24 years. The reason is that the annual number of visas allocated to the F4 category falls far below demand. You can track current cut-off dates on the Department of State Visa Bulletin.
The priority date is locked on the day the I-130 petition reaches USCIS and determines your place in the queue. Every year of delay in filing pushes the Green Card a year further out. This is why the soundest strategy in F4 is to file the petition the moment eligibility exists.
Do the Sibling's Spouse and Children Come Too?
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 in the same file as derivatives of the main petition. This means a single I-130 petition covers the entire nuclear family. Children turning 21 (aging out) can still affect the process; the Child Status Protection Act provides protection in some cases. For other family members, see our family reunification service.
Why Is Early and Correct Filing Vital?
In F4, the winning strategy is managing the wait. The earlier the petition is filed, the earlier the priority date is locked and the earlier the queue advances. Over many years, changes in the sponsor's and sibling's address, marital status, and citizenship must be reflected accurately in the file. You can see all stages through to citizenship in our family immigration roadmap.
