he stated ฿800,000 in your account for two months prior to the "initial application!!" He didn't state it needs to be back Upto ฿800,000 "two months" before the next extension.
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.
