What should I do if I wasn't given a TM 6 arrival card and need it for my 90-day extension in Thailand?

After re-entering Thailand, the user is concerned about not receiving a TM 6 arrival card, which they typically need to quote for their 90-day extension application. Community comments clarify that the TM 6 form is no longer required for foreign travelers arriving by air since July 2022. Users advise leaving that field blank on any forms related to the 90-day report or extension applications, and emphasize the importance of reporting arrivals through TM 30. There is some discussion about whether the user meant a 90-day report or an extension, with confirmation that many non-immigrant visas do require reports every three months.
