What visa options are available for U.S. military veterans living in Thailand with children in international schools?

Hello all! We are looking for people in a similar situation. Both my wife and I collect pension, roughly 284,000 THB per month combined, not including outside sources of income. We started working with Bangkok Buddy as a visa / travel agent, but after hours of research into the subject we are lost.

Quick bio of our situation, we are both U.S. Military Veterans with 3 children, we would like to put them in an international school, however we must figure out our visa situation before applying. Another thought that may be important to take into consideration with Visas, (having a Thai employee, aka Nanny). We are both in our 20’s so we don’t hit that 50yr mark quite yet lol.

For the expats in similar situations, did you stick to Thailand or move from country to country every 90 days? Please help us navigate this 🙏🏻 Thanks ya’ll!
