hi guys! i applied for my citizenship last month. i received receipt notice a week after. i checked my online status and it says that uscis mailed me an rfe (which im assuming is my fingerprint appointment) back july 9. its been almost 9 days but i still have not recieved anything through the mail. should i be concerned at this time or should i wait it out a little bit more. by the way i sent my application to the phoenix AZ office. has anyone had this experience before? thanks in advance!
