So I understand you have to bring a couple of recent passport size photos, as well as copies of pages in your passport plus your visa plus your entry form into Thailand, when you go to the Immigration office in Chiang mai to get your 30 day extension. Does anyone know of a place to get passport size pics plus a place to get copies made of your documents?

You can do it all at the Immigration Office - a little pricier than elsewhere but quick and easy.

Actually its not the immigration office. But a seperate building behind it.

Every place I have found that makes prints also can take your passport photos. The most important thing to remember is to specify the size you want with details down to size of your head and the size of your face. Take the diagram from the form and show them. Make sure you know what color background is acceptable.
