Do I need to report to immigration immediately upon returning to Thailand with a Non-O visa?

Arrrh the good ole' Korat tea and biscuit collection again... doesn't matter what anyone tells you they need your money and will happily take your money... it's what Korat IO do 🙄

When you say vacation, do you mean abroad or vacationing somewhere else in Thailand?

If you've left the country and returned, yeh it's best to re-register the tm30 when you return home (which you can do online with your wife - I assume you have your own property?... if not, your lndlord needs to re-register you, though you could technically do it yourself if you have the necessary docs)

For travel and vacations it isn't usually necessary, but I have had this issue for a short time in Chiang Rai back around 2018 when they started to suddenly enforce this rule even for travel inside the country, before stopping it.

Been told both ways . Io at airport said no need but others say yes . I just go to agent to do no stress no worries no fine

If you have a Non-O

12 month extension

And as John S mentioned correctly filed TM30 ,

No you don’t have to -

& your next 90 day check in is 89 days after you are stamped into Thailand again

I've never done it and I've been ok. I went OS 3 times in a year and no problem.

Must be which province you are in.

You are confusing your 90 Day report with your TM30 - and neither have anything to do with your visa.

When you first arrive in Thailand you need to do a TM30. For people staying on hotels or resorts this is usually done automatically by them, but it dirs bot hurt to check with them to make sure. If you are staying in private accommodation, or smaller independent hotels, resorts, guesthouses or Air BnB they will usually not do it for you, and you need to do it yourself or ask them to do it. In reality, if you are leaving the country within a month it will almost certainly not matter.

It does not matter what type of Visa you have - the TM30 process is the same regardless. The only other thing I would add is that if you left and re-entered on a multi-entry/re-entry permit or visa, and yiu return within a ‘short’ period (a couple of weeks, maybe a month) AND you are returning to the same address, then a new TM30 is not officially required, but the odd IO can be a pain and insist in a new one (TiT).

Re 90d reporting - again, the type of visa held is irrelevant. Anyone staying 90 days or more has to do a 90Day report, and the process repeats each 90 days. When you leave Thailand and re-enter the clocks starts again from Day 1.

The owner of your place has to do a TM30. 800 Bath was a fair fine. Is paying more years ago. I live in our own house here.

Sounds like wherever you stayed didn't file a TM30 for you. The landlord or owner is meant to do this within 24 hours of your arrival

It varies from office to office. I have never needed to go to Hua Hin Immigration on my return from abroad. Just go in and do my 90 day and nothing is said.
