From another forum:

Re-entry permit at CNX airport has moved from:

-BEFORE the security check on the left

to

-AFTER the security check on the right.

(The counter before security is still there, but they will direct you to the one after security)

Will depend on if it is a direct international flight from Chiang Mai as to whether you can use immigration at the airport. Everything can be done there including the forms and photos.

Examples:

You fly from Chiang Mai to Bangkok

You fly from Bangkok to another country

You must get your re-entry permit at the Bangkok airport

or

You are flying from Chiang Mai direct to another country

You can get your re-entry permit from the Chiang Mai airport

Just for clarification. Do you mean getting the re-entry permit at the airport itself or at the airport immigration office?

I had already been on annual extensions for 30 years for working at the university. So my experience is on renewing the extension and the WP. 🙂

@Wannikea ********

In Chiang Mai I have done it both ways with no issues.

They will only extend to the expiration date of the passport. So if applying for a 1 year extension and the passport expires in less than 1 year when you apply they will only stamp you to that expiration date. Personal experience. 😉

The US does require it to be mailed in as per the Embassy website and personal experience. Quite a few steps involved, I did a full write up of each step in a Chiang Mai group.

Took 6 weeks for me, others reporting 4-5 weeks.

@Ellie ******

and if doing it online after stamp transfers, you need to update your TM30. Personal experience. 😉

@Callum *****

That's exactly the same Receipt of Notification as I have. Mine was done in person.

As James mentioned, India now gets 60 day visa exempt entry. Sounds like your colleagues have old info or tried entering before the new rule came into effect.
