Hello

I have to do my first 90 report at Jomtien shortly and was wondering if there is any sort of supporting documentation required apart from my passport and completed TM47. 

Thanks in advance for any replies.

You will need some document that confirms your address in Thailand.  I use my 3bb internet bill.  This is usually only for the first 90 day report as on subsequent ones they just look you up in their computer and give you a new slip to keep in your passport for next time.

Proof of address should not be needed if you applied for an extension of stay at the office where you are making the report to since they are already have that in their records.

In over 4 years I've never produced anything other than my passport.  when reporting to head teacher. (Oh! when will this childish requirement end!)
