If things get better and borders open up they can end the amnesty before July 31. I read on Thai advice that they might not allow extensions after July 31st for people without proper visas but who knows. Anything can happen and change within a day. Best bet is to wait and check the news frequently.
My 6 month METV ends May 17th and right now no borders are open for me to extend till August so I might just head home July 31st.
Also if they do open up borders to travel out of Thailand, you won’t know what new requirements they want for you to enter back. Hopefully things get better and I’ll visit again sometime next year
I visit every year for 6-9 months with a 6 month METV, only down side is you gotta leave every 60 days or extend and leave every 90 days. Can extend up to 9 months if planned correctly.
They’re also cracking down on this if they believe you’re trying to live here on a tourist visa. If you have money you can get the Elite Visa
