Is it still worthwhile to submit my 90-day report in Thailand if I'm already 3 weeks late?

You go to immigration immediately and pay fine 2000 thb to the immigration agent

i didnt pay a fine when i was about 6 weeks too late 🙈

You're an idiot ... reap what you sow..

That's not about being useful or not, it's about following the law. There is a law with penalties (that are even tougher than the basic THB2000). Whether it's applied or not is the job of immigration, you may or may not be lucky. The report is an easy task and it's free.

Ok... if you are asking according to the law

Filing a 90-day report in Thailand, is mandatory for foreigners staying over 90 days,

Let's say you did not do, and you go to immigration for any reason or services that time you will be in a fine of 2,000 THB.

Again we are talking according to the law.. if it is implemented or not That is not our job, but the authority has the right to do

If caught by authorities without having a report, the fine increases to 5,000 THB...

There is a 7-day grace period after the 90-day period to submit the report without penalty. So you should be having enough time and if you are saying i forget , that is not an excuse

Because we always advise our clients

You have a smart phone and have a calendar

Put that in the calendar 7 days reminder before due

That will allow you 7 before and 7 after.

There is no excuse, unless you don't care the rules ,so if something wrong happened , No need to complain

And kindly... EXPERTS, we don't need you to comment or correct us.. .if you know better than us then that is great, keep your knowledge to yourselves

You should know the conditions of your visa and it's obligations. You have 14 days before the date and 7 days after or it's a 2000 bht fine. It's not about whether it's useful or not to report to immagration for your 90 days it's a condition of staying in Thailand. Whether you do it or not is up to you and as such you are fined. Don't do it and see what happens

After 7 days late you are fined 2000b no matter how late you are.

If you have no interaction with immigration you maybe won't get caught.

At some point you will need something, resident certificate etc. And you will get caught at some point.

It's not a big deal 2000b maximum fine If and when you get caught.

Id go to immigration and pay the fine if they come looking for you may be steeper mate cause now it looks like you are trying to avoid the rule. Just my humble opinion

You have 7 days after the 90-day date to file it.

But if you're not dealing with immigration before you leave the country, you can just skip it

You'll be fined if you try to do it now or later (until here, a fact). But, and this is something not verified by me: If you leave before the 180 day mark (assuming you're a DTVer), and then reenter later, "nothing" will happen. Immigration would still know you didn't file it, and they'll impose a fine IF you ever visit Immigration (not the airport) for any reason. But if you don't, nothing would happen. Again this is not any personal advice, just what I've heard.
