I got hassled at Sydney departing for Thailand with only 7k aud.
Money belt came up on the scanner.after they checked it I was followed to the flight gate and basically stalked by plain clothes authorities. I could see the idiots talking in the mic thingy. Heard one of them say he's sitting eating an apple. And that was me. Crazy
this advice was given to me by an agent. Who did not charge. They give one hour free. Phuket visa experts. They would charge about 25 ,000 bht to do all this once your here on 60 day tourist visa.
You need a non immigrant AO visa which you apply for and receive from the thai embassy in your home country before you leave your home country. You extend this each year in Thailand.
Health insurance is the most difficult thing at your age. If you can't get it you need to go about things differently.
Apply 60 day tourist visa from embassy in home country.
As soon as you arrive in Thailand open a bank account to deposit 800,000 bht.
Go to the immigration office nearest to you. They will give you a list of all the documents you need to apply for a 90 day NON IMMIGRANT O visa in Thailand.
THIS VISA DOES NOT REQUIRE HEALTH INSURANCE.
Once you have this you can apply for an Extension of stay for one year. Apply about 45 to 60 days after you arrive. You apply for this extension of stay each year.
