Should I pay a fine for overstaying my visa in Thailand or extend it instead?

why is the 2 days so important. why not stay 45 days?

Two day over shouldn't be a big deal. I've done it myself and it's had no affect on my getting visas or entering Thailand. Just don't get picked up while on an overstay.

It is always entertainingly strange to hear from these rebels without a cause. Getting the extension was the wise choice to make.

Safe journey to you always.

I'd be reluctant to just pay the overstay , although that's cheapest , you get a black mark as an overstay , I'd get the extension .

Visa extension place ?

Anyway just pay the fine imo .. over the years I’ve overstayed ‘ by a couple of days ‘ many times .. I think they’re quite happy for the income to the business actually..

Extend 30 days. 1900 baht. No overstay stamp I'm passport

If you never intend to return to Thailand then that's ok. Otherwise I would do all I could to avoid having an overstay stamp in your pp. I have one and it wasn't even my fault!

I'm not sure what you mean by "visa extension place" but you get your extension at the immigration office.

You should never go on overstay, especially now as they are doing a crackdown on overstayers.

If you are stopped by the police for any reason, even a random checkpoint on the way to the airport, you can be arrested and banned for 5 years from Thailand.

Also having an overstay stamp in your passport can cause problems in the future both trying to purchase a visa or enter a country, not just Thailand. Countries don't like seeing that you illegally overstayed anywhere.
