Can I extend my cancelled Non B visa after changing schools in Thailand?

The user inquires if it is possible to extend their Non-B visa, which was cancelled after they left their previous school during an amnesty period, and now work at a different school. Responses indicate that once a Non-B visa is cancelled, the associated work permit is also invalid. The user is advised to consult the Ministry of Labor for a work permit and to check with the Immigration Office about the potential for an extension based on their new employment.
