As far as Pakistani American , I would say they are very patriot and community knows everyone very well and well knitted. We have a huge contribution in bring community together but also play a vital role in raising funds for Pakistan in the time of disaster. Everyone knows who is who. Specially PTI is well organized in North America and all its active members registered in Pakistan. Some people start criticizing without knowing the facts. Every Pakistani in US has Pakistan origin card and registered in Pak NADRA. So, GOP has access to lots of Pakistanis in foreign countries. Plus, they are registered voters. We are mobilizing Pakistani to get their registration at fast track for next election.
So, people shouldn't worry about dual nationality. PMLn leader/Senator Mushadiq Malik family is US citizen, and he himself is green card holder.
As far as stealing wealth from Pakistan is very difficult and impossible to move to US banks due to strict money laundering regulations.
