The United States has a long history of debates and changes in immigration policies. Different groups have influenced whether immigration rules are strict or lenient. In the past, laws like the "Asiatic Barred Zone" limited immigration, while reforms in the 1960s led to more Latin American and Asian immigrants. Today, there are disagreements over issues like family separation and building a border wall. These debates show that immigration policies will continue to be shaped by conflicting views and goals.
