I am amused by the reporting of tightening of NZ/Australia/Singapore citizenship/visa norms in the Indian Media. Every country has their own set of requirements and they are entitled to do so. The obsession with such news is unnecessary. There are too many agrarian issues to cover out here.
One of the major reasons for the tightening is the inability of migrants to integrate and live within ethnic ghettos all their life. The effort on the Migrant to integrate is a lot more, as changing the colour of the passport should mean more.
