@Toby *****

no, the Extensions of Stay are 12 months

@Matthew ********

you only get an email if your last report was done online

Both, as above

@Rudi **********

You don't need an agent. As above you don't need an return or onward ticket at check-in (if asked for one ask to speak to the flight supervisor and show your Non-O). A Non-O Visa entry plus a Residence Certificate from Immigration should get you a bank account. Your accommodation will complete your TM30 so ask them for a copy as you'll need it for your Residency Certificate.

@John *********

on return not exit :)

@David *******

as stated above that "recommendation" is so that you do not apply more than 3 months out

no

If it mentions insurance you are not looking at the requirements for a Non-O but for a Non-OA which is a 12 month visa

@Ann-Louise *******

An Extension for the same reason as the entry stamp is added to the the current permitted to stay date not from the day of application

That used to be a requirement in Bangkok but not any longer
