I guess the point I was making is that lots of people own their own business for secondary reasons. Some do it for the write-off of expenses like phones, fuel etc. They are legitimate write-off's. Other people own their own business for the purpose of obtaining medical insurance through a company. So as long as there are no legal restricitions on the expat in question owning a business, yes they still can get company medical insurance with simply a DBA registered at the county records office.
