I have a friend who works in the call center at a day trading firm in Chicago. He's a sailor and the owner/founder of the firm has a boat so he gets long stretches of unfiltered time with the guy outside of work. The guy regularly affirms that they intentionally try to hire only HRI's ("hot russian immigrants") when they hire women because it boosts morale, makes hiring ambitious men easier and apparently exploits a small dip in the local hiring pool where the the immigrant women have a slightly harder time getting jobs at most places than the non-immigrant hotties they go up against elsewhere. My friend's firm found that going the extra mile to help them with visa status stuff meant they could get better looking women on staff than their competition.
