Where can I find the TM-7 form for a 30-day visa extension in Thailand?

Chiang Rai immigration in Mae Sai is where I went to today... one small photo. one copy of the passport photo page. one copy of the page with the entry stamp in the passport...they also made a copy of the receipt of current address which was stapled on the last page of passport... filled out the paper work and handed to the young lady... .... we arrived 1135am and was finished a couple minutes before 12 noon.. when they close for a hour for lunch... Chiang Rai immingration in Chiang Rai is extremely busy.. we wanted to visit the Sky Walk also.. Sky walk in Chiang Saen is better.. still... sky walk Mae Sai has a good view of the city..

Just go to one stop in soi 6 to help you with any visa application

Of course Immigration has the form.

Some offices will require a up to date TM30 but ask you local office about their requirements, plus you will need a passport photo as well.

You can either download it from the immigration website or your local office will definitely have some.

Yes, you get it at the immigration office. Each immigration sets their own policies and requirements so they vary from office to office. Here's a general list of common requirements.
