You will need to do a check ride first obviously with the place you rent the heli from , as for Reg's . there are only 3 types of airspace , a , c , and g . i would say 80 percent of the country is class g so you don have to talk to many people if you don't want to . Stay above 500' or 1500' over a populated area .
only difference you have is that you must file a flight plan to enter class c airspace .
Just make sure you have a valid medical and your licence is in date before you leave , as the american licence complys with icao standards , you can use all ppl privelages here. no insurance suplements needed as most of the r-22's for rent are under training insurance. . Nice flying over here but it can get windy and crap .
Give me an e-mail if you are coming over and i might be able to do some ground work here before you get here.
Safe Flying !
