Can I change my Non-ED student visa to a Working visa while staying in Thailand during Covid-19?

How about Non O volunteer to Non b?..is it possible to change?

It can be done in country but it is a multi-step process like this

1st step - you get documents from your school, you go to the immigration office that issued you your ED visa extension and cancel that extension (this is free)

2nd step - as soon as your extension is cancelled you apply for an "unable to travel due to covid" extension you will get an "under consideration" stamp telling you to return to the immigration office on xxx date.(1900baht)

3rd step - go back to the immigration office on that date you will get the extension of stay stamp based on not being able to travel (free)

AND

4th step - you can apply for an in country 90 day Non-B visa from that stamp (2000baht), it will also go under consideration and when you go back they will ink a Non-B visa and a new 90 day stamp into your passport (free)

In order to apply non-b working visa is you must leave country. If you don’t want to Leave and wish to stay longer is apply for a NON-O volunteer..

Go to the immigration...
