Oath ceremony scheduled in Troy Mi. The appointment letter mentions "No guests ". Can my husband come In at the uscis location at all or should he wait in the car? 2. How early to arrive before the scheduled oath ceremony? Like its scheduled for 1pm,should I come in at 12pm,11am or earlier? 3. When exactly are you supposed to complete the n445 questionnaire (does it need to be done in front of the uscis officer or can you complete it before arriving to the office)? And when to sign it. ....Anyone who had oath ceremony at this location, can you please share your experience. Thanks.
