If you are a U.S. citizen and at least 21 years old, you are eligible to petition to bring your brother or sister to live and work permanently in the United States. As the sponsor of your brother or sister, you must show that your household income is sufficient to support your family and your brother or sister at 125% or more above the U.S. poverty level for your household size. You do not need to file separate visa petitions for your brother's or sister's spouse or unmarried, minor children. Any child under 21 is considered a minor.

If you are a lawful permanent resident, you are not eligible to apply to bring your brother or sister to live and work permanently in the United States.
