Do I need to provide a police certificate when applying for permanent residence?
Yes. Applicants should provide a Federal Bureau of Investigation (FBI) certificate with fingerprints, and State certificates from all U.S. states where they have resided for a period of 6 months or more since turning age 18.
How and where do I obtain one?
You should:
get a cover letter and fingerprint card from the FBI. You can download these from the FBI website in the Related Links section at the bottom of the page or write to the address below and have them mailed to you.
have fingerprints taken. You can have this done by:
a local police department or
a private fingerprinting business.
(When you have your fingerprints taken, you will need photo identification.)
include a Certified cheque or money order for the fees, payable to the U.S. Treasury
mail the letter, fingerprints and fee payment to:
FBI, Criminal Justice Information Services Division
Attention: SCU, Mod D-2

Processing times are normally between 16 and 18 weeks. The FBI will send you the results of their check by returning your fingerprint card to you. That will be your police certificate. You should send the card and any attached documents to the Citizenship and Immigration Canada office processing your file. All police certificates must be originals. Photocopies will not be accepted by our office.
