@Louis ******
it's the ONLY way to get your degree from the US certified here in thailand.
Now as far as are they strict issuing in country 90 day Non-B visas, not any more than they were pre-covid.. The reason most employers sent a new employee out of the country to get a 90 day non-B visa at a thai consulate in another country was the requirements to get that visa there are FAR LOWER than they are to get the 90 day Non-B issued inside the country and many employers can't meet the in country requirements
SO it comes down to whether your employer can meet the documentation requirement for you to apply for a non-B inside the country AND in bangkok at least you need at least 15 days left on your current stamp to apply for the visa at the immigration office (because it goes under consideration for 14 days before you go back to get the Non-B and a new 90 day stamp inked in)
