@Terin *******
i don't believe that for a second. I know someone who gets yearly extensions based on retirement every year at the immigration office.
They show up, file ONE 90 day report (late), take the 2000baht fine, get the failure to file fined 2000baht stamp, then apply for their yearly extension and after that never go back to the immigration office the rest of the year
The next year they do it again, file a late 90 day report, take the 2000baht fine, then apply for their next yearly extension. They've done that 10+ years and have PAGES of failure to file 90 day reports on time fine stamps in their passport. They exit/re-enter the country on re-entry permits without any issue at all.
Those stamps don't hurt you in the least
