You can sponsor your brothers and sisters to immigrate to the United States if you are a native-born or naturalized U.S. citizen. If your brother or sister is married, his/her spouse and children who are unmarried and under the age of 21 can immigrate to the United States with your brother or sister.
- You can petition for half-siblings, step-siblings, and adopted siblings.
- To petition for a stepbrother/stepsister, you must each have been a “child” of a common parent. This means that they must meet the definition of a child under U.S. immigration laws. At least one of you must have been under the age of 18 when your parents were married.
