Once she leaves country they will need a Covid19 negative result test that is not more than 72 hours old, she will need a ฿100,000 (฿3.2 million) insurance coverage for each person, a border that is open as well as a 14 day self quarantine in Thailand after arriving and maybe a 14 day quarantine in whatever country they are going to transition through....a slush fund for accommodations and essentials is highly recommended...good luck like Tod said they should have bounced 2 weeks ago
No you have to schedule an appointment with the EV staff so they can make an appointment at CW for your visa to be placed in your passport...I believe you have to pay ฿1,900 for it
It will go on the last day of your visa exemption stamp...FYI if in BKK you can do the same day you arrive in country for a 30 day extension on your visa exemption stamp or at the 45 day mark on an SETV/METV...all other locations contact the local immigration office to find out their rules for extensions...cost stays the same everywhere at ฿1,900
