It is more likely under the discretion of Visa Approval Manager. I would suggest though you come early in the morning, as in you were about to be the first or second in line, at this time of the day, they are still considerate. Be sure that you have every requirement handy with you.When you're turn comes, just give them a nice smile and a peace greeting. I even new someone who's mother in law is almost 90 and they have approved it.....So good luck.....
