I recommend forgetting about citizenship. Never gonna happen. Either buy elite visa or wait till you turn 50 for extension based on retirement. Look at Dvt. You have a long way to go and you don’t sound prepared
sorry but your request isn’t simple. America is a great country. Norman , Oklahoma is not. I hope you visited Thailand before and have experience there. Good luck with what you are seeking. I spoke the truth.
uprooting your kids to a borderline third world country to piggyback on their educational visas is a lot of trouble for one year. Your family will give up too many concessions. If you HAD to for work , then I understand but you say you have money and are semiretired. Anybody with real money lives somewhere else.
