Please someone can tell me where I can extend my Visa for 1 more month in Bangkok,  Nawamin ...what is the nearest immigration office that I can go? 

Thank you

You have to do it at Chaeng Wattana immigration.

Map and other info here. https://division1.immigration.go.th/content/contact

Thank you..that's useful...

And another question:

What documents they need and how much the fees? 

The fee is 1900 baht.

You will need a completed TM7 form with a 4 X 6 cm photo attached.

Copies of your passport photo page, visa, entry stamp and TM6 departure card.

There are copying and photo services downstairs below the immigration office, and the TM.7 forms are just inside the immigration office door.

To make your life easier, download and fill in the TM7 before you go to CW

Also, do your copying before you get to Immigration (there are usually cheap copy shops scattered around)

That way you arrive with all your ducks in a row, present the paperwork to Immigration and it flows better. Well that's how I do it, anyway.

 

Look wholesome / smart - long trousers, collared or polo shirt. Remember it's a government office - apologies if that last comment appears obvious or superfluous but you'd be surprised at the number of people who turn up looking like scruff bags!

..and 100% of these scruff bags get their extensions approved too 

Thank you so much...I prepared what you said already...????????????????????????????????

Just out of interest.Have you rebooked you’re return flight and approximately what did it cost

I assume that when you entered you would have a return ticket matching your visa

Every copy signed by yourself at the bottom in blue ink.

Maybe....but I have seen (on Phuket, Patong beach Immigration office) someone effectively pushed back in the queue probably due to his personal appearance.

How do I know? 

He was first in the door, I was second. The IO looked us both up and down, then called ME to the desk first.  What happened after  I left, i don't know.

 

This has been discussed many times on TV, IMO if I'm going to a government office where THEY wear uniforms, I will at least make the effort to look and act with respect.

Right or wrong? Up to your own thinking, but what is definitely right is that I never seem to have any problems when I do it that way. So I shall continue to do so.
