What should I do about my 63-day stay in Thailand and potential visa extension?

I have same problem having booked ticket for 61 days. Staying in Bangsaray, can I just walk in to immigration in Jomtien or Rayong with ticket, passport and THB to complete 7-days extension or do I need anything else ? Thanks.

You could leave a few days earlier. Or, if that would mess up your return flight, take your gf to Phu Quoc for 3 days before 7th Feb. She'd probably quite like it.

A series of statements is not a normal question.

I overstayed once,couple of days,just pay the fine,have had no issues re-entering since.

You didn’t ask a question.

Alright see if I can cover the basics

3 days prior you can fill in tdac it's free, if you get one a site that one payment it's a scam

Are you saying with her? In her house or you staying hotel? If you are in her house you guys need to go immigration to fill in tm30 (24 hours after you landed) if in hotel they take care of that (you going to need that when apply for extension)

If you staying with her as said, ask the immigration officer when is the earliest you can apply for extension since differ from office to office, some 45 days some 30 and a few 7 days prior.

Never ever think overstay is a good idea.

When applying for extension I'll add a photo for you so you know the basic requirements

It's 63 days, so the only option is to buy an extension. I'm just surprised that this fact was not objected to at check-in at the departure point.

Take a week trip to Vietnam or somewhere else

59 days after the 7th Dec is 4th February (day 1 is your day of entry)

Without an extension it would cost you 1,500 baht in overstay fees and a stamp saying you overstayed.

Way better to pay 1,900 baht and get the official extension and not have any issues nor overstay stamps.

I think you can get a 7 day extension

Then your not using 30 day extension up

Should get an extension then you've no worries.

Just get a 30 day extension at immigration. No issue if it's your first extension.
