The smartest and safest path is to always update your TM30 before having any interactions at immigration.

So before you do your extension, you update your TM30.

This way your information is current and correct, raises no questions.

**our personal practice is whenever we travel anywhere, we come home and update our TM30**

@Darin *******

absolutely wrong.

There is no requirement for anyone to carry a copy of the Tm30.

We are required only to be registered.

There are no "spot" checks for tm30 ever.

The TM30 is used to locate you if the authorities need to get in touch with you.

It only comes into play when dealing with Immigration for extensions, residence certificates, drivers licenses, etc.

Most actual tourist will come and go without any Immigration contact ever.

This story lacks Information.

I don't believe he is being "hauled"

Away by immigration but rather somebody for the building taking him to get his TM30 registered at immigration.

Possibly warning him of potential fines.

An agent likely, who will charge him for their service.

Kinda scammy it sounds.

In my experience he will not get fined or possibly an 800-1600b at worst.

But lets see how it plays out.

@Marie *******

you will have no problem for a 30 day extension.

@Marie *******

EVERY entry is at the discretion of the IO you are in front of.

If you have no excessive history of entries, ED visas etc. You likely will have no problem.

AND usually will be warned to get a proper visa before being denied.

It is all discretionary.

There is no limit of 180 days.

If you stay more than 180 you risk being considered a tax resident.

As far as entries you can enter and stay as long as you are allowed, until an IO officer stops you.

@Munly ******

it's a leisure activity.

They don't care if you even do it.

Once you fulfill the qualifications and receive that visa there no follow up.

They are trying to boost tourism sectors and think that this visa will stimulate it.

Yeah its crazy but true.

@Edna ******

I explained the process, what they do and how many times is up to them.

You are also mistaken that you only get 30 days.

You now get 60 days Visa exempt and can extend it once in country another 30 days.

That's 90 days without leaving.

The Thai citizens can enter on the US passports on 60 day visa exempt.

Once in Thailand can then get their Thai passports renewed.

There will be no overstay or fines as they are Thai citizens.

You can visit your local immigration once in Thailand and they will explain the process of staying even though they entered on a foreign PP.

It's not a problem any longer to do that.
