i am on for a ban its common sense these people does not have any interests in Pakistan , they keep foreign passport as a back up , infact i think Pakistan should completly ban dual nationality .. a person should either choose to be a pakistani national or NOT. If he has lost hope than which many have than they should pick their country of choice and leave. after all our PM says WHO IS STOPPING YOU !!??
And we should not worry about foriegn remittance either .. banning dual nationality wont have much affect any way.
