About five years back I was recruited by them.  Didn't know who it was until I met them.  Went through a process of over a year of starting on the security clearance.  Took forever for them to tell me what services they wanted me to do (independent contractor preparing tax return for certain James Bond types - they randomly chose a few accountants around the country.  My biggest concern was security of my data files.  Would I become a target for hackers?.  One Sunday night a year later I get a call from my contact.  Thank you, program has been canceled.  Never heard from them again.  My guess is at that time I had an employee originally from Russia.  She had been in the U.S. for nine years. I had already let her go but again, that's just my guess.
