Hi guys,

I mistaken myself in the dates and found out my visa ends today instead of tomorrow. Will i be able to go to the Immigration Office in Jomtien tomorrow, pay for the 1 day overstay and get my passport stamped for an extra month, or would i have to go on a visa run thru airport? What are the costs of stamping the passport in Jomtien?

Thanks in advance for the info!

What kind of "visa" do you have ?

Before you realized this, when you thought it expired tomorrow, what was your plan?

All extensions of stay require a TM.7 form with 4x6cm photo and cost is 1,900 baht. With payment of 500 baht overstay they will likely allow your extension to be processed.

The OP wants another 30 days. This would be dependent on having a tourist visa.

A "visa" exempt entry would not be "extended" for 30 days in which case an exit/entry by air would be the best plan and would result in the desired 30 days stay.

I have a 15 days visa exempt as I crossed the border with Cambodia over land. I think I'm not going to take a risk here and find myself a roundtrip ticket to Laos

You won't get a 30 day extension from Immigration.

The most you can expect is 7 days to leave the country.

My plan before that was just to get a stamp for extention.

You were asking as if you actually had a tourist visa entry to extend but you only have a 15 day visa exempt entry so no extension is allowed on that. The most that could be obtained would be 7 days to leave the country on a disapproved application.
