The first comment is correct. There’s no going back to government amnesty. Advice visit nearest immigration office now. I only know that in Nakhon Ratchasima very helpful with a USA friend that had similar issues.
I’m beyond believe this immigration blog. A 90 day report takes 5 minutes. Go to your nearest office. Simply in Nakhon Ratchasima the last paper will be removed in passport and staple a new 90 day report. . It’s takes 5 minutes morons
