Hmm, a little bit of fun going on in here!
Capt Beeky, I can assure you no matter what WMU may say they will normally only offer you the J1 visa. Anyway, why would you want a H1B visa, you have to pay tax from day one, and the green card thing is a complete red herring. You must wait at least 6 years before even being allowed to apply, even then you must satisfy the IRS that you are a sound person to be allowed to stay for good, believe me, if you stayed that long in Michigan you should be sectioned, not citizened! To say they will take PPL instructors is putting it a bit too simply. They will train instructors up to 509 level, but you have to have a lot of experience as an instructor (1000hrs+), or airline training experience. Also, you will only be on single engine for up to a year before they train you for your multi instructor ticket. The Extra is a carrot, forget getting to fly it!
