I sometimes wonder what "or eligible to obtain the required authorizations" means. Does that just mean that SpaceX has to sponsor the clearance process for you?
I remember reading another thread where they were talking about one or two non-US people working there, it would be nice if they elaborated more on what the process is for foreigners and maybe had some profiles of non-US people in their employee gallery. Even confirmation from a SpaceX person here that they do have people like that would be nice :)
