We originally applied on 12/22/2021 and received an interview date of 3/24. We received a call in the morning on 3/24 telling us the A-file has not arrived and the interview will be rescheduled. We received a new interview date of 4/28 that same afternoon.
We attended on 4/28 and was approved. We had a 310-day period where we were out of the country, but the officer didn't ask too many questions as we submitted enough paperwork to demonstrate intent to maintain domicile. Attended the same-day oath ceremony.
