For admins...also you need a new letter every month they said. So in theory if you get the extension and next month you can not get a new letter, you also can not switch to an ed visa, thus you would be forced to leave the country.
So better to apply for long term visa this month, instead of getting extension because next month cant get long term visa
TLDR : Answer Summary
The discussion highlights the importance of obtaining a new embassy letter every month for visa extensions in Thailand. It suggests that if you cannot secure a new letter for the next month, you may be unable to switch to an education visa (ED visa) and may have to leave the country. One commenter expresses concern that taking the amnesty extension based on an embassy letter might limit options for future visa changes without exiting Thailand. The conversation concludes with uncertainty regarding the ability to apply for another embassy letter or extend one's stay further.
