Been looking at the visa requirements for type rating.
FlightSafety don't issue I-20-Ms for anything other than the academy where you do your ab-initio stuff, not any of the learning centres, so you can't get an M-1 for those.
They furnished me with the letter from the Dept of State, but London Consulate just regurgitate the paragraphs about "if you're going to study you need an M-1 etc"
The whole lot's just a bloody great mess ! Do you go, don't you, who do you believe ?!
