I was not aware that those two issue were actual legislation but more of a regulation put in place by earlier regimes more similar to the original Obama DACA executive order. DACA originally failed in the legislature. anyway those issue need to disappear as do anchor babies.
The Immigration and Nationality Act of 1965 (H.R. 2580; Pub.L. 89–236, 79 Stat. 911, enacted June 30, 1968), also known as the Hart–Celler Act,[1] changed the way quotas were allocated by ending the National Origins Formula that had been in place in the United States since the Emergency Quota Act of 1921. Representative Emanuel Celler of New York proposed the bill, Senator Philip Hart of Michigan co-sponsored it, and Senator Ted Kennedy of Massachusetts helped to promote it.
Chain migration became the driving force behind immigration to the United States in 1965, with the passage of the current version of the Immigration and Nationality Act. The 1965 legislation changed the objective of U.S. immigration policy. Rather than admitting immigrants who were likely to assimilate to our culture and succeed in the United States, American immigration policy shifted its focus to an extremely broad concept of “family reunification.” This placed the integrity of immigrant families above the economic, national security, and public safety interests of the American public. As a result, the pool of immigrants eligible to come to the United States became largely self-selecting.
