"No, immigration is not mentioned in the Constitution. The founding fathers didn't think to include it because they were more focused on formulating a system of government and securing the nation's independence. Only later, with the addition of the 14th Amendment in 1868, citizenship was extended to all persons born or naturalized in the United States, including immigrants.
The Constitution gives Congress broad authority to enact laws regulating immigration, which it has done over the years through various statutes. The most recent and comprehensive immigration law is the Immigration and Nationality Act of 1965. "
