You should check out Mauna Loa Helicopters in Hawaii! I have been out here doing my training for the past year and they have been great. They have locations on the Big Island (main location), Oahu or Kauai. We get a lot of foreign students here from all corners of the world. They also have student housing which is very affordable for Hawaii and everyone that lives there is a student.
Hope to see you out here,
Ed
