My father was foreign-born, and immigrated to the US, where I was born.

Did the immigration authorities then screw over their own kids by letting him in?

Did the US screw over their own kids by accepting Cuban refugees during the 1960s? By accepting Hmong refugees in the 1970s?

During 1860-1910 the percentage of foreign-born in the US was about 14% - very close to the current percentage. Did the US screw over their kids then?
