Update: USCIS just reversed its decision and allowed back Amit into the country. (Source: he just posted on his facebook wall).
I know Amit and how hard working he is and am very thankful this was resolved so quickly. At the same time, I hope it grows into something more than just a lone media frenzy-induced example. If the US is to stay competitive, it needs to reconsider its immigration policies. (Full disclosure: I am a foreigner myself).
