Define "immigrant"? Honestly, that can mean any class of things in loose definition of the term. I bet some Senator on the Intelligence Oversight committee, says legally speaking if your definition is everyone that is not Native American - you are an immigrant - just to fudge the law, until someone says you can't do that. The perverse intelligence community can only become perverse, if both the public holds the government accountable, but then the body of oversight - Congress, our elective official body of representation (noting the President doesn't really count anymore) - makes it so. It's gonna eventually happen, if it hasn't already started as of a decade ago (or more).
