I'm planning to move out of the country after transferring my managing director position to a person who's currently holding a STV.

My company is eligible for only 1 WP so I believe I need to cancel my WP first then issue a WP for the person who's taking over.

I've contacted an agent a week ago but they were not quite sure about this.

I'm curious whether

1. Is it even possible to convert an STV to Non-B in country now?

2. What are the typical processes of transferring a WP to a new director?

Thank you.

Ubonjoe was right all along ????
