This week, we take a look at the asylum seekers returning to Afghanistan after being deported by European authorities. An agreement signed between the European Union and Kabul last October called for the return of 80,000 migrants whose asylum applications had been denied. People are being deported daily yet with little improvement in the security situation in Afghanistan, and rebuilding their lives there is often an almost insurmountable challenge. Also, we meet the Chinese families who send their children to the United States to better their prospects when it comes to higher education.

And we check out the chart-topping hits that are breaking down barriers in India, as a new generation of music fans shuns the social divisions created by the caste system.
