Those three months are completely unnecessary.
I would also like to talk about the types of interviews that are done at the first stage at the visa post in Hong Kong. At the visa post in Hong Kong, many of the interviews are done over the phone, where credibility cannot be easily assessed.
There's no system in which they say, okay, this is what we're going to do: we're going to have you come into the room, we'll ask you questions, and these are the standard questions that will be asked.
You can't assess credibility over the phone. That's why there's a 50% refusal rate. That's why there is such a high positive determination at the IAD.
