Because my acceptance for registration part 1 was only for 6 months, I took a risk and flew to France to enter and get the visa at the port of entry.
I got a 30 or so minute interview, which was nerve wracking to say the least, and came with every bit of documentation I could think of in hand.
Since I had a return ticket booked for November, I only have clearance until then, and I'll have to reapply when I'm in the US for a full student visa.
But this means I can register next week, get my student loan money, and actually be enrolled and on the way to my PhD.
YAY!
(and the Suitehotel in Roissy-en-France is a sucky place to spend a night alone.)
