Do I Need an FDLE or FBI Background Check for a Foreign Residency Application?

If you're putting together the file for a foreign residency application, the immigration authority is likely asking for a U.S. background check. The question that comes up right away is which one: the state-level FDLE check, the federal FBI check, or both? The answer isn't the same for every case, and guessing can cost you weeks of delay in processing your application.
There's no universal rule: each immigration authority decides whether it accepts the state-level FDLE check, the federal FBI check, or requires both. Confirm directly with the authority or consulate processing your residency application before ordering any background check. Once you know which one you need, order the certified version and follow the matching apostille route: state-level for FDLE, federal for the FBI.
