"Part of the application is a FAA medical? Being an international student do they accept the CAA class One Medical?"
You need to get an FAA class 1. A JAA class one is not acceptable, but the FAA medical only costs between 60-100 USD and is not as stringent and is easy to arrenge once you get here.
"Whats the conversion process from a Frozan FAA ATPL to a JAA ATPL?"
Basically 14 JAA exams and a multi-instrument checkride in a JAA member state.
FSA is an extremely well run school where you are treated properly as a customer. Their aircraft are in very good condition and well maintained. Flight instruction is second to none in my own personal experience. It is an expensive school, but I do believe that you get what you pay for in the flight training industry. I do not work for the school, but I would not hesitate to recommend it to anybody.
