Oh yeah, you betcha. We had more than a few who moved on to bigger and better things. Not one of them to my knowledge had a problem with getting their VISA.One of our Dominican nieces worked as an engineer in two different SD area free zone factories ( I think Cardinal Health and Playtex). She was head-hunted from there to a fantastic job in Oklahoma.
I know of at least ten who are now Plant Managers in other Free Zone companies.
