it may be because of the limit on his/your debit cards. My U.K. card is limited to £300 per day!! It might be worth looking at the rates, and cost, of sending yourself Thai Baht, with Western Union. 🤔
Contagion is a myth, that people have been brainwashed about for generations. Doctors and scientists have been trying to prove contagion, for over a hundred years, without success. Some of the trials were absolutely disgusting. At the time of the Spanish Flu, these included ill patients actually spitting in healthy people’s mouths. No healthy people ever “caught” any illness from any of these attempts to prove contagioun.🤷🏻♂️
My understanding is that, when the 1 year validity is getting close, a new health insurance policy needs to be bought, you leave Thailand; and you re-enter Thailand, just before the expiry date of the Visa.
You will then be stamped in, until the expiry of the new insurance policy.
Day 1 is when you get stamped in to Thailand, even if that’s 11.55pm!!( in such a case, better to wait until after midnight)
In your case, getting the additional 30 days, which is added to the original 60, not from when you apply, you need to count the 90 days, for your return flight.
For example, if you arrive on 2nd March, your 90 days expires on 30th May.
