What are the reasons for being denied exit and re-entry at the Mae Sai border or an extension at Chiang Mai immigration?

As this topic totally went into the interesting way to how set I up a business in Thailand I close the commenting. To set up a business you need the help of a Thai lawyer of Thai accountant, they will help you and answer all your questions how to do this.

Rejections at Mae Sai - and as Todd notes they simply won't let you exit vs stranding you in Myanmar, are rare. Presuming you haven't done your two land border bounces in the year you should be fine.

There are more reports recently, however, of people having a hard time getting 30 day extensions at CM Immigration if they have a long term history in Thailand on visa or visa exempt entries with extensions.

I am going to caution EVERY member on here.

STOP making value judgements on the visa questions people ask.

That means STOP IT NOW...

It is NOT your business what type of visa they want to be here on. It's theirs.

Either provide answers to their questions or give the post a pass and keep scrolling.

As far as denied an extension.

On a 30 day visa exempt stamp YES, I have seen people from countries who are allowed to get one get denied at the immigration office and sold a 7 day extension denied stamp that gives them a week to get out of the country. <- IF you're denied a 30 day extension on a 30 day visa exempt entry stamp you automatically get the extension denied 7 day stamp to get out of the country in a week for 1900baht. There is NO appeal process for this, you either get the 30 day extension OR you get the 7 day stamp to get outta dodge.

On a valid 60 day tourist visa NO, I have not heard of anyone from a country who can get a 30 day extension on a 60 day tourist visa being denied. I am not saying it doesn't happen, I'm saying I haven't heard of a verifiable case <- meaning it sure doesn't happen all that much.

okay they won't even let you stamp OUT of thailand at the Mae Sai - Tachiliek border with Myanmar IF you can't stamp back in. That's because you can't go anywhere IN Myanmar without having a valid visa NOT just a day pass so you'd be stuck at the border town.

You don't allow others to document their experiences if requested?

This page is called Thai Visa advice, but you do not want advice. I assume you are on the wrong page.

working on line in Thailand and living in Chang Mai, so get yourself the work permit and the Non Immigrant B visa. Than there is no reason to be scared to do the so much needed visa runs.

The reasons

Let me flip your question around. Do you believe you will be denied entry at the Mae Sai border?

There will be for sure people who are denid at that border and there will be people denied Extensions of Stay. But what is your Thai Visa question?
