Yes, it’s true you now need an M1 visa. Previously an ESTA would have been suitable, but I understand ICE are cracking down on the training providers for accelerated type ratings or standard type ratings. Recurrent training can still be done using an ESTA.
An M1 visa is a lot easier to obtain than a B1, some countries have a wait of 400 days before an interview at a US consulate for the B1.
However, if the training provider won’t issue an I-20 then you have a problem.
