maybe if you have a document that confirmes that you are enrolled in a course and even better if it would say that your studies arent finished yet its gonna be easy (i had a paper that confirmed that my classes were finished one week after my visa expired) but even if bot you will be fine i think, its your first entry on visa exemption for this year!
I was in a similar situation. Visa Exemption + Extension, 12 months ED Visa, wanted to take a study break before going for more thai classes. crossed the border and could get in straight on a 30 Visa Exemption. Got asked a lot of questions though, since they are careful with people on ED Visas because of the illegal work situation.
Would be interesting to know, why they write, that you could no longer apply.. the webpage says that they changed collecting days and stuff but they do not mention anything about cancelling that servicw
Not me, but a friend. She did it in the last 3(?) Years a couple of times and after sending her passport she always got it back within 2-3 weeks.
She applied again via post like 5-6 weeks ago and didnt hear anything. She called them several times and nobody answered. She is waiting and doesnt really know whats going on. By the beginning of next week she will go there and figure things out.
