My school said they will provide the paperwork (but it was around 7-10 days ago). The question mostly - will immigration office do this extension with paperwork or not?
Yes, I'm talking about the same nationality. Not sure how it works for different nationalities but maybe it depends on a country you are trying to enter. Anyway, they asked me to show an old password to see the exit stamp.
Ok, I have some time until May so will try to find the best and less-risky way. Just don't want to leave my family here in Thailand for 7 days so trying to find some workarounds. Thank you for your responses!
Maybe it makes sense to try Vientiane with new passport in 360 days and if they denied I could wait 7 days there and apply with the same documents? I don't know whether it's possible or if they denied then new documents are required
