Be quite. I am not beneficiary for NIW, however, I respect the people who work on science. the less chances they have, the less pay they get. I used to working in the pharmacy schools as a ph.d student. Most Ph.D students work day and night and get a little money. Pham.D. Students enjoy their life and get almost 100k/y as soon as they graduate. What we are doing is to discover a new drug, while what they are doing is to count pills. Which is more valuable for the society?
