I still don't see how that is equality before the law. That would be like saying that by virtue of being a culturally backwards world citizen in another country we must grant you the chance to pollute our country the way you did yours. Cultural preservation is a legitimate object of government and to allow an invasion of non assimilating outsiders in to the country would reverse the preference away from the welfare of American citizens and toward the culturally jacked up migrant. I don't see how this is equality before the law from our point of view. Europeans assimilated quite well in only a few generations. I can't say the same for a few other countries who share neither the culture that made advancement possible in the United States or the ability to assimilate into that culture.
You aren't very smart are you?
All people, regardless of national origin, have a right to enter the US. Before 1965, they didn't.
I agree, immigration laws before 1965 were preferable to today's laws. The point is, equality under the law is not necessarily a good thing, case and point this example. Equality before the law can be a very bad thing. Things were better when we discriminated based upon national origins(when we didn't treat people equally under the law).
