The Thai Immigration Department for Trat Province has a new home having recently relocated from Laem Ngop to its new purpose-built building in Klong Yai.

Please note; The Trat Immigration office in Klong Yai is about 10km before the Hat Lek border crossing to Cambodia. If you reach the border, you have gone too far!

Thai Immigration Department Office - Klong Yai - Trat Immigration

The small sub-office of Trat Immigration is still open on Koh Chang island for expats to register their 90 days place of residence but for all other visa related business, you’ll have to trek the 80km or so to Klong Yai.

For tourists looking to extend their Tourist Visa, you will have to head to Klong Yai too.

It’s a bit of a trek, so make sure you have all your documentation in order and remember to take the following items with you.

  • Your valid passport
  • A completed visa extension application form (available at the immigration office)
  • A recent Passport size photo
  • A photocopy of the main pages of your passport
  • A photocopy of the page showing your current visa stamp and Departure Card
  • 1,900 Baht

Photos and Photocopy Shop in Klong Yai

If you don’t have a recent passport photo or photocopies of the relevant passport pages, there is a service behind the Immigration office where you can get these items done but don’t rely on them being open. It’s a long trek and it would be advisable to go prepared to avoid doing more than one trip or incurring an overstay.
