I was working in Thailand, I had some problems at my home so I resigned at the company, the employer said he is not accepting my resignation and is not cancelling my visa or work permit either. They kept my passport (old one which had all my visas and shows my travel history) which they have still not returned to me.
I want to go back to take some action against them but I want to go on my own visa.
I want to know how can I figure out if they have cancelled my work permit and visa to Thailand? What way can I confirm if they have or have not cancelled my work permit and visa?
