<human>:  Can you help me understand the different perspectives on immigration policy in the United States?
<bot>: The perspectives on immigration policy in the United States vary depending on the political and social views of the person discussing the topic. Generally, the perspectives tend to fall into two camps: those who are pro-immigration and those who are anti-immigration. Pro-immigration supporters typically believe that immigration is beneficial to the US economy and cultural vibrancy, and advocate for forms of comprehensive immigration reform that would create pathways for undocumented immigrants to get legal status and eventually citizenship. Anti-immigration supporters, on the other hand, tend to view immigration as a threat to the safety of US citizens, the economy, and national security. They may advocate for stronger border security and a zero-tolerance approach towards undocumented immigrants and may oppose any form of comprehensive immigration reform.
