Chiang Mai to Bankok return

[jimmysjo]

Do I still need a permission from the Chiang Mai Amphur office to make an essential trip to Bangkok?

Is there any other documents needed?

And what when coming back to Chiang Mai?

Flying there and staying for two nighs.

When did you need permission?

Well, latest 23 Feb. I know much can change until then, but how will I know? Ask the airline? I want to book as soon as possible, but I guess they won't know in advance.

Nightmare: standing at the airport without the necessary documents.

So, I wonder what the situation are now. And how I can check what regulations are in force later.
