<human>:  What are the immigration policies of the United States?
<bot>: The immigration policies of the United States are largely established by federal law, which includes the Immigration and Nationality Act of 1965 and other related laws. These policies seek to ensure that legal immigration is safe and orderly, while also controlling illegal immigration. The laws also provide legal protections for certain immigrants, including refugees and those seeking asylum in the United States. In addition to federal laws controlling the immigration process, states may also enact policies regarding entry into their state.
