Frequently asked
How long until I take the citizenship test?
USCIS typically schedules the interview and civics test 6–12 months after filing. We include free civics-test practice in your dashboard.
Can you come with me to the USCIS interview?
As a document-preparation service we cannot represent you, but we make sure your packet is complete and you are well prepared.
Guinea Services provides document-preparation services and is not a law firm. We do not give legal advice. If your case is complex, we will refer you to an immigration attorney.
