OKLAHOMA CITY (AP) — A federal program in which information about legal and illegal immigrants is shared is being expanded into eight more Oklahoma counties.

U.S. Immigration and Customs Enforcement officials say the program uses biometric-fingerprints taken from immigrants who are arrested for a crime. The fingerprint is submitted to the FBI for a check against criminal history records held by both the FBI and the U.S. Department of Justice and is shared with the Department of Homeland Security.

If the fingerprint matches a person in Homeland Security's system the process will notify immigration officials. ICE then can determine if the immigrant is in the country legally.

ICE says Canadian, Cleveland, Garfield, Grady, Lincoln, Logan, McClain and Pottawatomie counties were brought into the system Tuesday. Tulsa and Oklahoma counties were already a part of the information sharing program.
