Hannah Romero Nullan thank you... I am not looking to cancel my Non B extension.. i am looking to switch from yearly Non B to Non O without changing work permit. i did not mentioned anything about cancelation.

Steve Grier. thank you . that is what exaclty i am looking for. bu ti need more clarificaiton. my Non B extension will expire on 14 Novemenber. before how many days i should apply? 30 days or a week ? 0 baht required from which dates.

Thank you for advise. is there any specific time to apply as my visa is end on 15 Nov. when should i reach out to immigration to cancel my extension based on employment. also what i heard that my employer need to pay social security for only 2 staff once i switch. is that correct? please advise the complete documents required thanks a tons

@Tod ********
