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
If in BKK you can do the day you arrive...outside of BKK check with your local immigration office to see what their policy is...cost is ฿1,900 for 30 days
If you’re in bkk you can do it 45 days out...if not in BKK check with the local immigration office to see what their policy is on extending visas...cost is ฿1,900
