Hey y'all!!!
He was in the waiting room for four hours. He called me at 12:30 PM and this is what he explained about the process:
A number of applicants were in the waiting room at 8:30 this morning just like him.
An officer came out and handed each of them a nylon package to put their documents in (passport + criminal record clearance in my husbands case).
They remained in the waiting room for hours and then the officer came out again and returned the applications to them, including the IMM forms and any photo evidence or correpsondence.
He then told them to return at 2:00 PM today to collect their passports.
We are assuming (and so are the other applicants he was speaking with) that this means he will get his visa at 2:00 PM.
I know I should probably wait but I already booked his plane ticket, and if God is Willing, he arrives Friday afternoon!!
So the long and the short of it is that there was no interview, and I will know this afternoon if he does in fact have the visa today.
Thanks for all your help everyone + I will keep you posted!
