My parents were also immigrants to a new nation (Australia), and they also had many immigrant friends from various nations around the world. Both of our nations (Australia and the US) were built on the backs of immigrants who migrated to seek and build a better place of opportunity for their children. That is the sort of drive that propels them to do great things!
