The whole process has become amazingly bureaucratic now. Even the "plain language" guide referred to above is over 10,000 words.
And it all seems so misdirected. Surely now, anyone even 1% as suspicious as the 911 hijackers would be spotted straight away by any flight school, visa or no visa.
It must be an incredible burden for the flight schools.
BTW thanks for the offer, englishal, but I've already been to Vegas and come back. Hoover Dam looks spectacular from the air
