My Thai wife and I are opening a shop house in Rayong.We are going to have a small store,with 7/11 kind of stuff.Also a small cafe with a bar.I am only there 3 weeks every 3 months.If when I'm there I want to cook on the grill or in the kitchen or make drinks or play my guitar.Do I need a work permit?She is going to be the owner or 51% owner.
