Hi Bose-x,
No problem at all.
If you do find that the $100 SEVIS fee is payable would you be able to let us know?
Ta!
Hope you have a good trip once you get through the loops and bounds.
Oh and just a quick side note... the "interview" at the Embassy itself lasts for ooh around one to two minutes. No need to get stressed about it at all.
Best wishes,
Charlie Zulu.
