I should add that the fact the US Govt has insisted on proper visas should be the point that the company says to those concerned that the gig is up. Time to go home, wherever that may be. If the US Govt has an issue with 'documentation', then basically it means they shouldn't have been there in the first place. Whether they have '10 years seniority' or not is irrelevant. How can ANYONE justify the company undermining the 'ownership' of a particular base slot against the interests of that country's own nationals. Imagine if they started doing that to other bases, there would be howls of protest. This issue is NOT going to go away quietly....I am sure of that.
