Can 90 day Non Imm O visa from Vientianne be extended for 1 year at CW?

                                 Thanks

Yes if you qualify for a extension of stay. Upon what basis would be applying for the non-o  visa and extension?

By all means you can obtain your non O retirement at Vientiane OR you could border bounce enter visa exempt that will provide 45 day stamp and obtain your non O at immigration.

800k in your Thai bank account on the day you apply. 

That will provide a 90 day stamp and time to season money for 12 month extension.
