my first 60-day expires on March 12. I think I will apply for the 2nd covid extension in chanthaburi. I don't know this immigration office, I am a bit worried

That explains all. Even though I have visa exempt entry with first 60-days covid extension on top, I am a bit sceptical about the prospect of second 60-day extension coming up next month. I try to figure out which immigration office would be best to increase the chances of approval as it seems every office has their own interpretation.

$600 is not that bad at all. But 3 year ban hurts.

Can you please tell us what kind of visa you originally held and later extended due to covid19. Also can you let us know which immigration office? Bangkok?

I had to do roughly 1 YEAR (YES 1 year) overstay in Turkey in 2020-21. It was right after when the pandemic started and all my flights to Europe and USA were canceled, airports were shut down, huge panic and no vaccine. I didnot feel safe returning to USA while >3000 died daily and half of the US claimed there is no pandemic, just a fake news. I paid around $130 USD at the airport for 1 year overstay and 3 months re-entry ban, that is it. I travel extensively, this was my first overstay at all, would never do it in normal times. It was great to get away with just $130. It would cost me $5,600 USD and life-time blacklist in Thailand, or even a capital punishment or execution on the spot, God knows.

@Florian *******

may I ask the reason of refusal for extension?
