Interview approved then status changed to RFE
Interview was set at 7:30 AM.
We were up by 5:30 AM to get ready and prepare the kids.
We arrived at the USCIS office at 7:05 AM and they opened the door at 7:15 AM.
It was us and another lady. Then another woman and a gentleman arrived.
At 7:25 they called on my wife and of course did not allow any of us with her (unlike the green card interview).
After 5 minutes, they called the man, and the 2 ladies shortly. A 3rd woman arrived and went inside.
A nice lady (seemed russian) arrived and waited for 5 minuets before she was called.
