No such thing as a covid visa. The unable to travel due to covid extension is being extended.

1) re-entry permit

2) if at university yes, if doing non-university course then it's much harder and unlikely

3) yes but you need to be attending class in Thailand or your student visa will be cancelled by the institution. Unless you have a dodgy visa of course...

No

go to the embassy, e-visa isn't available in Cambodia to the best of my knowledge.

Probably best to start looking at the requirements on the Dutch Embassy in Thailand's website

No. You might be able to get a covid extension if you apply before 24 May but short of extending it for the reason you got the visa you don't have many choices.

@Michael ******

ok you've edited your post so it's clearer 👍

Don't need either to enter Thailand.

Your last thread suggested you were on overstay, is that not the case?

@Dipali ***********

he's supposedly unable to travel due to covid hence being on said extension so no he won't be able to get a re-entry permit for it. Nothing to stop him from trying though.

There's nothing stopping him from leaving the country but he'll need to go through all the hoops to get back into Thailand, including obtaining a visa should he need one to re-enter.
