I’ve read that the 1965 Immigration and Nationality Act replaced the national-origins quota system, but I’m trying to understand how much that changed immigration in practice. Did the new rules immediately shift where most newcomers came from, or did the effects build over several decades?
I’m also curious about the role of family reunification in the law. Was that mainly intended to bring relatives of people already living in the United States, and how did that priority shape later migration patterns?
What’s a good way to separate the law’s original design from the longer-term outcomes it helped set in motion?
