60 day Tourist visa extendable one time for 30 days giving total 90 days. Visit your local embassy site... Theres also a an E-Visa site you can visit,,, I don't have any knowledge about this as it's new.... I'm sure someone will pipe up in a few minutes with a link.
60 day tourist visa. Special Tourist Visa, Non O, Non B, Non ed, NonR, Non RS Depends a bit on your reason for coming to Thailand. Costs vary depending on Embassy
Always try and make yourself aware of public holidays in your host country AND, should you be in a position to do a visa run in the future.. public holidays of the country youre visiting to get said visa... got caught out once on that one in Kuala Lumpur for a long weekend
Ok, so now you're on overstay, you cant get any kind of extension on overstay so now theres nothing to extend (no fine for today as yesterday was PH) . I think you're out of options.
Yes, you need to do a 90 day report. That said, it depends on what immigration office you use. Koh Phangan has been trying to enforce it with mixed results. Getting your extension renewed does not automatically re set your 90 day report, however some offices do that for you. Go and speak to them at immigration to ask how they are dealing with it this week. As has been mentioned, it's free to do, after the initial one is completed you can then do it on line with the new app/website that seems to work pretty well.
Where in Thailand are you? Phuket immigration have been conducting hotel visits for this exact situation. You or your hotel need to contact immigration. If they do not know they can't help you.
