The majority of U.S. citizens are not in favor of illegal immigration to the United States. It is a security hole that should be fixed with a border fence that works reasonably well and additional measures. There is something of a war for sovereignty of the nation going on presently with foreign nationals proving up that they rather than the U.S. government rule borders and immigration. The U.S. has been losing the war for some decades.
