Because contract probably does not say remote work. Get a letter from employer stating that you are permitted to work from any country worldwide including Thailand
Mail a visa? No embassy mails visas. They either tell you to collect your passport on x day or send you the evisa. If that concerned why not split out the balance into another account just leaving the 500k showing? Or if you are that rich just get the Elite visa
well they accepted mine with Xe rate but thks concern. Im sure embassies dont use a SuperRich or the like rate to calculate balances they will use something like Xe as it is the proper rate.
Anonymous participant if u need a visa and have all the other supporting documents. I did a post re my Hanoi experience a couple of days ago so take a look as that might help
