Sorry to burst yer bubble, but probably no chance of employment as a seaplane instructor with that time. Most insurance companies won't even cover hull insurance until 200 on type/category ie: float. Then you would have to look at immigration paperwork, you would have to leave to apply for the visa, an LMO would have to be done, employer would have to post it for 2-3 weeks and not have equivalent/higher qualified people apply. So many more places in the USA, we have fewer airplanes than alaska, that says it all
