I was never told by immigration at bkk that i needed a non o to enter thailand just that if i wanted to stay longer than 30 days to get a visa so hopefully it goes the same when i fly in june
the problem with that is i already have a non o visa in my passport, which is why i was very briefly questioned upon my last entry in 2021 but as soon as i showed immigration my return ticket they let me in they just said if you want to stay longer get a visa
