After filing an application for naturalization with the United States Citizenship and Immigration Services, it typically takes 3 to 5 weeks for an appointment notice for biometrics to arrive. At the appointment, fingerprints are taken for a security check.
The notification about the biometrics appointment will provide a application support center location where fingerprints and photographs are taken. The FBI will conduct checks for criminal activity and against databases of individuals who were caught trying to cross the border illegally.
The appointments last about half an hour although at peak hours there could be a lengthy wait. After the appointment, a receipt is issued to prove that the applicant attended the appointment. The next step in the immigration process is to wait for a notification about an appointment for naturalization, which usually arrives 3 to 5 months after filling.
