Came back to Thailand yesterday and found out that TM 6 arrival card is no longer required. After some reading I found out its 'temporary' measure, only if you arrive by plane.
Now, when I have to extend my visa in December, I'm worried that immigration may ask me for TM 6
Did any of you have experience of doing a visa extension without the TM6 form? How did it go?
TLDR : Answer Summary
The TM 6 arrival card is currently temporarily discontinued for all entries into Thailand, including those arriving by air. Concerns regarding its necessity for visa extensions appear to be unfounded, as previous experiences shared by other expats suggest that no TM 6 is required when applying for a visa extension. However, it is important to ensure that a TM 30 form, confirming your address in Thailand, is on file with the immigration office.
