I am on dependent visa F2.
For getting PCC of USA , we filled the application form of FBI and went to the nearest US post office to give the fingerprint.
We were able to process only my husband’s since he had US Driving license (they will do only for persons having US driving license or US passport).
I dont have US driving license and SSN, hence they didn’t process my fingerprint.
I read that it can be done from local police station in the below link
Please let know the documents they ask in local police station for getting the fingerprints done.
