now,
VISA
As far as the Visa Waiver is concerned, I just found a table from the ICE (US Immigration and Customs Enforcement) that explains:
"Nonimmigrants, Who Can Study?" (
http://www.ice.gov/doclib/sevis/pdf/...an%20Study.pdf)
Apparently
"Visitors" CANNOT study except if the training is "merely avocational or recreational in nature"
I guess the Immigration Officer rather let's you go, then to find out how to bust your chops
I try to find out more... maybe somebody should call Flight Safety or CAE Simuflite and find out if all their foreign clients flying Jets/Helicopters merely for fun?
I stand to be corrected.
