Exporting Knowledge Via Students
Granted, I'm from canada, but work as an undergraduate student on a civil engineering project, with the brains being an Iranian post-doctorate student. The foreign students always seem to be the hardest workers around the University, it's incredible. Even if I consider myself generous of my time, most of these people never look at the time, and pull incredible shifts, coming in during the weekends and staying late to finish off presentations for next week. I cannot imagine this being any different in the USA. I'm not sure governement workers will pull long hours to grant those permits.
Modern day research cannot allow itself such a blatent chokepoint.
