, well, at first glance, it makes it all seem bogus, but then, even the U.S. will charge you (a lot) extra for expedited service. Was your receipt for 1,900 or 3,000? That would say a lot.
Also, this explains why, even though it usually takes a few weeks for this process, a sign out front states that you can come in up to about the day before your current visa expires.
