While the five-year-old South Asian University (SAU) is gaining traction, one worry is the rules are different for students from different countries. The university's few hundred students come on a special South Asian visa (except, of course Indian students), but those from Pakistan have to contend with a 'one-city limit'. This means they need special permission to travel to Gurgaon or Noida. Since the SAU attracts students predominantly from the Saarc countries, one wonders if this is the best way to encourage regional cooperation in South Asia.
