Thank you a lot. I will go to BOI in person on Tuesday to ask them if they could tell me what my options are. This all visa thing is so relative. For example, I wanted to go out from the country (to Laos) on 26th October and not to make a re-entry which means that my visa would be cancelled by default (although my WP would be cancelled on 31st October but who cares). And then I would apply for non-immigrant O and come back. My WP is being cancelled on 31st October and I would have my fresh non-0 and apply for WP but some guy on Thai visa (ASEAN NOW) told me that there would be a danger they would give me an extension but not non-0. I will do this by myself and hopefully learn something new and share it here. Thank you very much once more ...
