Absolutely correct. I'm 65 a fitness fanatic gym, walking,and a healthy diet. This might not be a surprise to you but I am not in need of any medication whatsoever.😊
It also might be worthwhile mentioning that depending on your age Health insurance in Thailand can be extremely expensive. Check out the costs before you choose what visa to get.
If you apply for your Non immigrant O Visa in your country they ask for funds in an Australian bank. When applying for my one year extension they were not remotely interested where the funds came from. But as we all know, immigration offices don't all have the same rules.
Do it yourself, I just got a year extension the other day. Immigration speak english, and are so helpful. I took advice from the guys here. They were right it's easy.
