Yes, but it is one of the most challenging family petitions due to the long backlog. U.S. citizens can file for a sibling by submitting Form I-130 and proof of the family relationship. Unlike petitions for spouses, parents, or unmarried children under 21, sibling petitions are not classified as “immediate relatives.” Instead, they fall into a capped preference category, which means the U.S. issues only a limited number each year. As a result, siblings may wait 10–15 years, and sometimes longer, before a green card becomes available.

Yes, U.S. citizens can sponsor siblings for a green card, but it is often the slowest family-based immigration process. Unlike immediate relatives (spouses, parents, and minor children), siblings fall under the F4 preference category, which is subject to quota restrictions. Depending on the sibling’s country of birth, the wait time may exceed a decade. For some families, it may be faster to explore alternative pathways such as employment-based immigration, diversity visas, or immediate relative petitions through other qualifying family members, if available.
