I received a new British passport and went to Phayao immigration to transfer non o visa extension from old passport as it still has 6 months to run no problems took. 90 minutes quite surprised no Embassy letter needed

Hi all, i’m currently on the 30 day tourist visa exempt and i’m looking to extend it for another 30 days at either the Chiang Rai or Phayao immigration office. Would appreciate help with 3 questions:

1. Will the extension start from the day i apply or from the day my original 30 days end?

2. What documents beside my passport and passport size photos are necessary?

3. Is the tm30 form needed? And if so how do i get it? I’m staying with a local thai friend in their apartment.

Thanks in advance!

At Phayao immigration today got my remaining 11months inked in on my yearly extension non o marriage based took all of 10minutes and only required my passport after my 1 month under consideration period
