I am a Vietnamese-American considering taking a job in Hanoi with my company this summer. My wife is not Vietnamese and I have two boys (9 and 7) who having been born in the U.S. and raised here until now, don't speak but a few words of Vietnamese. I've done some very light research on International Schools in Hanoi but most of them are VERY expensive (as expensive as the best private schools here in the U.S. where I live now); as much as Protected content U.S. I can't afford that for two kids. Does anyone have any information/recommendations about decent international schools or where english is the primary language of instruction that are reasonably priced? Dual language with Vietnamese would be excellent. If they are all this expensive, are there any other options?
