Why do I need to get my TM30 stamped if my address hasn't changed?

I’m all for an ankle bracelet...save a lot of hassle

It is likely to never happen but as I suggested before: A Government Issued Long Stay Expat photo ID card as done in places like the Phillipines would achieve all Expat Alien whereabouts reporting problems.. I invision a Required Issued for a fee ID Card with an online updatible member account with password. The mandatory 24 hour address reporting and even 90 day reports could be part of the features and benefits to both the Government and Expats.. The current cards in use Pink, Blue - whatever don't suffice because many Expats are not married nor do they 'own' property.

The card could have a smart chip in it with all Alien info/data. This card could also serve as a Residence Certificate for obtaining a driver license, bank account, assist in obtaining a marriage certificate and more..

Actually I think Thai Immigration will someday adopt such a card for long stay on all annual Extensions of Non Imm visas.

Yes

And with a house book with my name on it they still technically require this ?

The Border Immigration and the Internal Immigration Departments are not linked by a Database. That is why the Internal Immigration Department keeps asking for you to report your address within 24 Hours of you returning to your registered address. It's actually the Landlords responsibility to register you as returning. However, that responsibility nearly always falls onto the Foreignor. Also dependent on where you live different Immigration Offices interpret the Rules differently......Most in Isaan don't want you to come and notify them of your address.

because "right hand doesnt speak to left hand" so to speak. Welcome to typical government "efficiency"

They essentially want to know your whereabouts at all times. So, anytime you enter the country your address MUST be reported to immigration within 24 hours. It's the law. When you're just reporting back into the same address, it's easier/less time consuming.

What visa do you have...? If just on a tourist or VE, then there is pretty much no reason unless you will be extending later.

Don't sweat it George, US immigration are worse if you are not from there.

Yes, you have a new Departure card number and day of arrival in your passport.

The reason is to report your address if you stay at a private address, to update the TM6 Departure card number and the day you arrived. Depending on Visa or Extension of Stay, if you are able to stay longer than 90 days inside the country, you can only do the 90 days reports on-line if the correct details are updated in the database.

The reason is because immigration and sections 37 and 38 of the immigration act says you have too.
