The answers to your questions are exactly as m'frog posted...
My question to you is this...Why WOULDN'T you want to be there for the interview?
Do you know what happens during the interview for a fiance visa? The first thing they are looking for is that the RELATIONSHIP IS FOR REAL...therefore, you NOT being there for it, sends up a BIG RED FLAG...
And if your fiance wants that visa, is it that much trouble for him to travel to the capital? It seems to me that it's a smalll price to pay for the coveted visa...
What do you mean 'is this the only time'...****, if you guys really wanted this, you would be jumping through hoops to get it...
Seems to me that this is either a sock puppet or not a very solid relationship...
