Just so you're clear you're not extending anything 😮 What you're doing is exiting the country to get off the current stamp you're on and entering on a NEW 180 day entry stamp. It's not any type of extension just a new entry 🙂

Now as to your question;

The only land border between thailand and burma that's open is the one you get to by boat from the Ranong pier (Ranong/Kawthaung)

It's a tightly controlled exit/entry point and you'll pay what the boatmen want or you won't get out of thailand.

If I'm not mistaken (which I could be 😉 ) it's about 2500baht to bounce out/back at that crossing.

the online system is not complicated, just don't get ahead of yourselves

1 - first make a profile/user name

2 - then add an address to that profile

3 - then you can select that address to file a Tm30 for someone on

4 - then once you save the data of that person you search for it and export the file giving you a PDF you can print that is your TM30 receipt

read the user guide, it's in thai or english

your ultimate goal at the end is to have this paper

@Chris ******

no problem at all, immigration is right and you shouldn't have an overstay if you can avoid it but I just wanted people to know a short overstay or a single day isn't really going to affect anything they're doing inside the country

If you're in Chiang Mai

@Jacquii *****

then you're good to go get the extension any time.

You can use the main immigration office by the airport OR you can go to the satellite immigration office in Central Festival Mall

Either one will do 30 day extensions on free stamp/tourist visa entries

Okay let's sort this out before this thread goes sideways with people whose intentions are good but information might not be 😮 🙂

First - doesn't matter when you apply for a 30 day extension on a 60 day free stamp or 60 day tourist visa entry, the 30 days is always added to the expiration date of the existing stamp. This means there is no advantage to burning down the stamp to the end because you don't lose days by applying early.. 🙂

As far as WHEN you can apply for the extension that is controlled by the immigration office you use (where you're staying in thailand)

Some offices (Bangkok, Chiang Mai, Samut Prakan, and others) allow you to apply when you have 45 days or less left on your stamp

Most other offices allow you to apply when you have 30 days or less left on your stamp

BUT

A few offices (notably; Jomtien & Samui) only allow you to apply when you have 7 days or less left on your stamp. <- I don't know why they're just renegade in that regard

Also just in case people are wondering

IF your current stamp expires on a day the immigration office is closed <- weekends or holidays, and you go the very next day they are open you can get your extension like normal, you will not be fined for overstay (you will get a stamp in your passport that says "overstay xx days fine waived due to closure") and that won't affect you entering or getting a visa, or getting an extension at all..

Best of luck to the O/P, just GO get the extension this or next week sometime and you'll be fine.

@Chris ******

there is no "bad report" on anyone's' entry/stay history because you have a single day overstay,

in fact when you fly out of the country with an overstay of under 24 hours you don't even get fined OR get the overstay stamp, you get a thai language stamp only that says overstay under 24 hour fine waived"

Even a short overstay doesn't affect you getting a visa/extension or entering the country like people imagine it does

@Jacquii *****

At Bangkok/Chiang Mai and a couple other offices you can do it when you have 45 days or less left on your current stamp,

Most of the rest of the offices allow you to do it when you have 30 days or less left on your current stamp

BUT

A couple renegade offices (Jomtiem/Samui) only allow you to apply when you have 7 days or less left on your stamp (dunno why they are just wacky that way)

I think you're confused a bit.

When you apply for a 30-day extension, that time is added to the expiration date of you current stamp

There is no benefit to wait until your stamp runs out to apply for the extension because you don't lose any time applying early.

Is it easy enough for your family to file the tm30 online using the web portal?

That depends on how savy they are with Thai websites, there's a user guide have them read it.

You won't be fined because immigrations has no idea when you left the hotel and actually showed up at that address,.

So have them make a user account, have them add an address, then have them file a tm30 on you and download the receipt.

Just so you understand, you're not going to apply for any marriage visa after this 90 days runs down. You have the 90 day non-o Visa already based on marriage, all you going to be doing is applying for a year extension based on marriage when you have 30 days or less left on your current 90 day entry stamp

You should go to your immigration office, and get the handout listing the requirements to apply for that year extension as far as photos, documents, copies, etc.
