you wont just pick up thai unless you are a very talented polyglot. You will have to study it. Portuguese won't help you learn thai, they have nothing in common at all.
I can assist if you are considering krabi or trang provinces, we have extensive land holdings and are currently building two residential villa projects. Happy buyers are too busy enjoying their life to tell everyone about it on fb.
Wow good to remember. I knew about this as a tourist but hadn't thought about it as someone working in Thailand. If I leave on a re-entry permit, does this still apply?
