What laws have been passed regarding immigration what did they do?

Various Immigration laws have been passed over the years, addressing issues such as border security, visa regulations, and pathways to citizenship. For example, the Immigration and Nationality Act (INA) of 1965 eliminated national origin quotas and prioritized family reunification and skilled immigrants. More recently, the Deferred Action for Childhood Arrivals (DACA) program, established in 2012, provided temporary relief from deportation for certain undocumented immigrants brought to the U.S. as children. Additionally, laws like the Secure Fence Act of 2006 focused on enhancing border security through physical barriers and increased enforcement measures.
