Can I file multiple immigration petitions at once?

Yes, It's allowed U.S. immigration law does not limit you to one petition at a time. You can file multiple I-130s or other petitions for different family members, or even multiple petitions for the same person under different categories.

You can file multiple I-130s for the same person if multiple qualifying relatives exist. Example: both a parent and a sibling file petitions for the same person, USCIS allows it.

Each petition requires its own USCIS filing fee, so it can get expensive if you're filing for multiple people.

Filing multiple petitions is not considered fraud or abuse. As long as all information is truthful, it's completely legal.
