Did he "not" get the 30 day extension because they're not offering a 30 day option for the "covid" extension?
It sounds like OP wanted the standard "30 day for 1900 baht extension" one uses to extend when they come -- which has allllways been standard issue (1x only)
Not sure if the new site looks like this or not but I ignored the "print" options at first / didn't look closely because I didn't need to print anything.. without realizing that I need to click it to see the next appt page
Happened to me while I was home in Canada for a month - wet passport completely damaged
Got a new one using the expedited process
Visa/extension of stay/re entry permit all void.
Was able to get a new "sticker" for a new visa put into my passport from the Thai embassy (consulate?) in Toronto... Was able to sort it all out but a pretty expensive mistake!
