Hi,
We had our interview on March 16th. Our officer looked kind of young too and wasn't very nice, frankly.
At the end of the interview, she said: i'll have to review your case and see what my supervisor says.
We asked if background check was completed or not- and she said she'd check on that as well (wouldn't give us a 'yes' or 'no' answer).
5 weeks later, we got an approval email.
My question is- do you know if your background check has gone through? That seems to be the main reason why most people wait so long. I think, even with supervisor approval, one may end up waiting for a long while, if FBI check is not completed. I don't think just a supervisor approval by itself should prolong the case too much.
Maybe if you gave us the DO where you had your interview- someone else from the same DO, could give you more specific information.
