@Benjamin *****
as the photo of stamp: I entered Thailand on 10th January 2020 with NON B single entry that is expired on 10th April 2020.
So now under Amnesty.
Meanwhile I had Extension 30 days unavailable to travel with letter embassy.
My question is: can I still apply for 1 year extension of my NON B?
In alternative, can i convert my NN B in Volunteer or Study Visa without leaving Thailand?
