Hi..just do visa run in Cambodia..who told you about that tax clearance? That's not true..and why the sch did not do anything extend her work permit?..renewal of WP is very easy..bcs it is just to submit the same docs as her previous visa with the new contract & with new validity on it..my school renews my WP and visa as early as 1 month before it's expires.i am working in the same sch for almost 7 years now.renewal of WP and visa is the easiest thing to do rather than to go to Lao and process new non b again and process new WP again.she must go out Thailand today or else she will be fined 5h/day kha
you got your visa.you don't have to worry..it's ok if u will not mention about your gf too..just come as tourist..that's ok because you got already a visa..don't have to be scared...maybe immigration will just ask you where will you stay here?..u will be perfectly ok..
