You missed my point, I was not refering to terrorists, I was refering specifically to PRC spies and covert military. Also, I think you are naive regarding what is required to hire an H1B who is a PRC national. I know, I've hired such people.
Oops, I read PLO rather than PLA. In any case, the Chinese are actually they're pretty open about their intentions. They are now encouraging their ex-pat scientists and grad students to go back home and are providing incentives to do so. We get much more from importing bright people in anycase. I would prefer to get more of them to stay. The family friend I wrote about in my earlier post was recruited by Chinese agents and offered $1 million dollars to disclose what he knew about lasers and high speed semi-conductors. They even threatened to confiscate his new factory in Shanghai. He refused and reported this contact to the FBI as per his post employment contract terms and post security clearance requirements. Of course he's ethnic Chinese from Vietnam like myself, so he hates Communists as much as I do.
I'm not going to sit here and deny that there are spies and moles. There are and I hate them worse than anyone because it casts apsersions on myself and other loyal immigrant-citizens. But I'm going to stand by what I said about corporate security. If it's valuable, it's probably closely guarded and if it's not then it is not worth sweating over.
So are you saying that you knowingly hired PRC spies and covert military through your H1B program? Or was it just paranoia?
