ATTENTION MEMBERS
It appears to be a confirmed fact (because people are being turned away at immigration offices all over the country)
IF you entered on a 30 day visa exempt entry OR a 60 day tourist visa entry BUT went on amnesty you CANNOT get a 30 day extension now even if you never got the first 30 day extension you were "entitled" to apply for.
The second you went on amnesty you lost that ability
IF anyone has gone to their immigration office on a 30 day visa exempt entry OR a 60 day tourist visa entry that is on amnesty and got a 30 day extension please report it here
TLDR : Answer Summary
An important update for expats in Thailand: If you entered the country on a 30-day visa exempt entry or a 60-day tourist visa, and subsequently went on amnesty, you are currently ineligible for a 30-day extension. Reports indicate that individuals in this situation are being turned away at immigration offices nationwide. Even if you hadn’t previously applied for the 30-day extension you were entitled to, entering into amnesty means you have forfeited that right. However, there are variations in practice between different immigration offices, and some users have reported successful extensions in unique circumstances. The community is advised to stay informed for any future official announcements regarding extensions as the current amnesty period draws to a close.
