F4 — Brother or Sister of a U.S. Citizen
The sibling green card — the longest queue, which is exactly why filing early wins.
Overview
U.S. citizens aged 21+ may sponsor siblings, with the sibling's spouse and under-21 children included. F4 waits run 15+ years and up to two decades for some countries. The priority date is the single most valuable asset in the case — we file immediately to lock it.
