not that precise, he just stated ฿800,000 before his next extension, he should have said the balance needs to be ฿800,000 two months before his next extension 😂
I replied to Dave Athertons comment, he said he overstayed by 16 days, so 16 days at ฿500 a day overstay fine = ฿8000 + ฿1900 extension = ฿9900, I don't understand how his fine was ฿16,000, I'm missing something but I don't know what 😅
Ask the owner of the house your staying in to do it, if they won't do it, I believe you can do it yourself on-line with your landlord's assistance, by providing a copy of the house book and Thai ID card, there is an option to select "foreigner" and enter passport details (make sure it's the new website) make sure you screenshot it and print it, although I've heard now on the new website you can select a PDF and print it.
I assume you're talking about a 60 day single entry tourist visa?? Applying through the Thai e-visa system?? I think it depends where you apply, at which embassy/consulate, some take a few days others have reported waiting for months, you just need to enter Thailand before the validity period ends, it's valid for 3 months from the date of issue to enter Thailand, if you mention your passport nation you will get better advice.
