It was a long wait but the interview lasted about 2-3mins. Make it short and to the point, don't reply with a long story.
It went very smoothly, thank God!
Quite a lot of people were turned away because they did not have a cashiers order, some brought personal checks or thought credit cards were accepted. They had to go off to the bank and return later in the morning. By that time, the queue would have grown longer.
TIP: If you have very thick documentation (like I have from the lawyers), make sure you go through it, use a Post-It sticky and label the supporting documents. This will make it easier for the officer processing your documents.
