I mean it says that you can work anywhere. It does not explicitly say you can change completely to a new employer, but it also doesn't explicitly say the opposite.

Same thing?

What if on a non o based on marriage.. then the whole thing has nothing to do with immigration

@Robert ******

.. I am not saying you are incorrect. But I personally interpret the text differently. Do you know for a fact from the Thai website that what you say is correct, or is it your "safe" interpretation?

Being allowed entry, in however form or shape is always at the discretion of the particular IO you hand over your passport to. Be friendly and polite, and its not out of the question to ask for something. I also had friendly IO's (thai and laos) sqeeze in exit and entry stamps in on otherwise full pages in the middle of my passport, because I only just had two full pages left when I went to Laos to get a SETV, where the Laos visa and TV alone takes two whole empty pages.

There is no requirement to stay any length of time. Just go around the building after stamping in to Laos, and stamp out again, take the bus over the bridge again and stamp in to Thailand

You will have plenty of time for that.. boarder closes at 10pm

Oh it just dawned on me you mean the note next to the visa and red stamp.. Never mind me.. I will just go hide in a corner now ;)

I have that exact same stamp on my non-o single entry based on marriage, from Vientiane. Since then been on 1 year extensions.. Asked my wife just now, and she say it just says the same in Thai as the English text under: "royal thai embassy Vientiane"
