You can go to the Thai Consulate in Kota Bharu and apply for the One Year Non Imm B Visa Multi Entry. I am reasonably sure one has to be a Company Director.

Or you can go to Penang and apply if you are listed as a Company Mananging Director in the Work Permit.

Consider a couple of years under a Multi Entry Tourist Visa (6 months using a series of 60 days stays and 30 day extensions - the 6 months can be stretched to 9 with proper management

For what would your Non Imm O status be? Marriage ? Because it too can be to begin a 'retirement' (leading to a one year Extension of stay and volunteering) Thus my confusion

Apply for the Non Imm O-A Multi Entry Visa

The financial proof is supposed to be the Equivalent of 800,000 baht in bank account - isn't it?

Howard Waudby - correct - except you don't have to get Extensions

Without Extention - leave in 60 days (border bounce) With Extension of 30 days - leave after total of 90 days (border bounce)

Liquid Account are good words

There is also a cover form letter prepared by a Labor Ministry officer.. The WP.3 can be receipted same day with a stamped copy given to your employer's staff member or to an agent. The cover form letter may be done quickly or it could take several days ... Your representative who goes to the Labor Ministry may be required to show to the LM officer photos you take of the Thailand Exit Stamp and the Malaysian Entry Stamps in your passport (sent back by Messenger, Line, WhatsApp, etc.) before either document is sent
