Yes, U.S. citizens not green card holders can sponsor their brothers and sisters.

You’ll start by filing Form I-130 (Petition for Alien Relative) for each sibling you want to sponsor.

You must file an Affidavit of Support (Form I-864) to show you can financially support your sibling.

It’s important to stay updated on the visa bulletin to track how close your sibling is to getting a green card.
