As I said Miss its could be any thing ,,,,,,,,, it could be a simple ban on dependents entry or there right to work Australia and UK as example in some Cassese. And even a 50% American must policy will effects horribly.
I am not happy about it as I spent lots of years out side Pakistan ,People (immigrants) work really hard some times 12 to 18 hours a day (even legally) just to have good living , better life and well being for there families back home but I am saying it to those Indians who are jumping with joy on "May be a ban on Pakistanis".
