You do understand you're beating a dead horse here. The person you describe has no path forward here in the USA unless, unless he has the skills and desire to survive here.
Will you have to live in your vehicle (if you can afford one)? Yes you probably will have to unless you have family support.
Oh my but where will I shower and use restrooms? I would join a 24 hr gym or one who opens early and closes late. Exercise and shower there.
Or, you can stay in Jomtein, have a condo with AC, beach right there. No need to own transportation, can eat out everyday if you choose or cook at home. Can easily afford an agent to make immigration problems go away. $1200/mo will get you a decent life in Thailand, back home not so much.
