Even if we went back to the days of Ellis Island, we didn’t have open borders. In fact America has always had strict rules about how you go about becoming American, some well-founded and some outright racist.

If you mean federal laws that imposed restrictions on who could enter, live in, or work in the country, then it is certainly not true that the U.S. has always had such laws. There were no such laws prior to 1882.

If you mean federal laws that impose restrictions and define procedures for immigrants, once they have arrived and set up in the U.S., to achieve status as naturalized citizens, then it’s true that the U.S. has always had such laws. But naturalization laws aren’t the primary issue in debates over “open borders.” The primary issue is the right to cross the border freely and to live and work where you choose.

And we’d have to figure out rules to govern who could stay in the country while their application was being processed, and what kinds of things they could do during the waiting period (Work? Go home for a visit? Etc.)

What business does the government have subjecting a peaceful Mexican immigrant to a higher level of scrutiny or restriction in the right to engage in everyday activities such as working or visiting home, than they would subject an American citizen to, simply because the object of their scrutiny happens to be Mexican rather than American?

Isn’t that just institutionalized bigotry?
