U.S. citizens may need a "certificate of good conduct" abroad or proof that they lack a criminal record. You may need this for various reasons, including adoption, school, or work.
Go to your local police department where you live or last lived in the United States. Police departments may need you to be there in person to request the background check:
The Criminal Justice Information Services (CJIS) Division of the FBI provides a range of state of-the-art tools and services to law enforcement, national security and intelligence community partners, and the general public.
For a fee, the FBI offers an Identity History Summary. This summary is also known as a criminal history or "rap sheet." It includes information from fingerprint submissions. These data cover arrests and may also include federal jobs, naturalization, or military service
The FBI will not provide copies of other people's arrest records to you.
Go to the FBI webpage to learn about how to request your FBI Identity History Summary.
If you need to use your background check abroad, you may need authentication and either an Apostille or a non-Apostille authentication.
Authentication
Apostille
You can send FBI and police records to the U.S. Department of State Office of Authentications to get an apostille if necessary.
