I guess I have a similar issue (hopefully). Great interview, she said just wait 2-5 months for a letter.
We come here, read many people getting Oath invitation and my anxiety goes over limit.
I am still IP (partner got DM next day of the interview).
I called CIC a couple of days ago, lady went to check, said (with a very friendly voice) “everything is fine, just wait for a letter” and she confirmed the address was correct.
And.... nothing changes.
Mine is still “IP”.
Not sure if ATIP will be of any help ?
It’s not easy to wait! If I was grabbing extra docs or getting FP I guess I would be happier, at least it would have some “action” going on!
Good luck!
