We're trying several approaches to getting info, including rewards and even immigration opportunities. The incentive that motivates one person might not be effective at motivating another. There's also the notion that someone who lives in a dangerous area overseas might be more willing to come forward with intelligence data if he knew we were willing to help protect him and his family through relocation.

In practice, this idea of offering permanent residency with the opportunity to become a citizen isn't all that different from the Witness Protection Program (WPP). In order to win convictions against organized crime, the WPP sometimes gives a new identity to people with very unsavory pasts including murderers. If someone provides valuable info against terrorist plots that could save lives, I'm more than willing to overlook an immigration violation or even more serious crimes.
