Sibling-to-Sibling Petition: Requirements, Steps and More
Table of contents
A sibling petition allows a U.S. citizen over 21 to sponsor a brother or sister for permanent residency in the United States. It is one of the most requested — and most competitive — family-based immigration categories, with waiting times that can stretch over a decade.
This guide covers the requirements, the step-by-step process, and what to expect in terms of timelines. If you need legal guidance, our family petition lawyers at Zava Immigration Law Group are ready to help.
What is the sibling-to-sibling petition in the USA?
A sibling petition is a process through which a U.S. citizen over the age of 21 may bring his or her siblings to live permanently in the United States. This is done through Form I-130 and, once approved, Form I-485 is filed for status adjustment.

However, beneficiaries should not enter the country with a pending application. If they do so, they could face severe consequences. Therefore, it is best to seek the advice of an attorney. Don’t risk your family’s future. At Zava Immigration Law we can help you. Contact us and secure the future of your loved ones.
