You will need to complete the online arrival card up to 3 days before you arrive

@Ray *********

no, you report or pay the fine, no other consequence

All correct regarding your new 12 month entry stamp

Do you mean day 90 or day 75, the first date you can report?

@Frank ********

You know your work schedule so it should be possible to plan it

Just like everyone else you apply online

You can get an extension yourself in 6 weeks

@Paul *******

There isn't one for a Non-O

You submit your eVisa application and get emailed a receipt which you print and take to the Embassy or Consulate between 9 and 11am the following day to pay the fee then wait for approval or further contact.

Arrive with your Non-O, get a TM30 from your landlord/hotel, get a Thai sim registered against your passport, get a certificate of residence from Immigration using your TM30 then use these along with your passport and Non-O to open a bank account. Ideally do this in the first week or 10 days to enable you to transfer the 800k which needs to "season" for 2 months prior to applying for your 12 month extension at Immigration in the province where your latest TM30 is filed.
