Hello. I mailed the N-400 app for my wife and myself to CSC around June 15th. USCIS received it around June 19th. I have received the receipt notice and the fingerprint notice for myself. But nothing yet for my wife - not even a receipt notice. Anyone here with similar experience? Anything to worry about? I am planning on calling them tomorrow to find out. Anything I need to keep in mind? Any/All help will be greatly appreciated. Also, both our checks have been encashed.
