If it's any consolation to anybody, here in France it's the same problem to have your D visa renewed... But here it takes 2 days !! First day is for interview and second day is for visa issue. So for all of us who don't live in Paris, that means having to take a trip up there, pay for accomodation, etc etc and being greeted by less than sympathetic embassy employees who also b*** off for their lunch break.
A friend of mine had his visa refused despite him going for a renewal... had his previous us visa for over 10 years and for no reason whatsoever, new visa was refused. US embassy explanation: he has the same first and last name as somebody on their "black" list. He is a pilot who often flies to US and so now is grounded because of this, hasn't flown for over 2 months now as problem is still not solved. His boss (the owner of the private jet he works on) wants to fire him now 'cos he's "useless" to him without a US visa... Nice story eh ?
