Hitting the immigrants with those laws!

There were many laws established in order to keep immigrants from entering the United States. For example, the Immigration Act of 1891, made an Office of the Superintendent of Immigration within the Treasury Department. The Office of the Superintendent was in charge of “admitting, rejecting, and processing all immigrants seeking admission to the United States and also implementing national immigration policy.” At the U.S. ports of entrance, there were immigrant inspectors that were ordered to collect manifests of passengers that were coming into the United States. The largest station of the U.S. ports was located on Ellis Island, which was in the New York harbor. In addition, every immigrant that was entering the U.S. ports, was charged fifty cents by immigrant inspectors.

The United States Immigration and Naturalization Service which is also known as INS was associated with the United States Department of Justice. INS used to work with the legal and illegal immigration and naturalization. The United States Immigration and Naturalization Service was then transferred to the Department of Homeland Security in March 2003. The Department of Homeland Security is composed of three agencies, which are U.S. Citizenship and Immigration Services (USCIS), U.S. Immigration and Customs Enforcement (ICE), and U.S. Customs and Border Protection (CBP). "The administration of immigration services, including permanent residence, naturalization, asylum, and other functions became the responsibility of the Bureau of Citizenship and Immigration Services (BCIS), which existed only for a short time before changing to its current name, U.S. Citizenship and Immigration Services (USCIS). The investigative and enforcement functions (including investigations, deportation, and intelligence) were combined with U.S. Customs investigators, the Federal Protective Service, and the Federal Air Marshal Service, to create U.S. Immigration and Customs and Enforcement (ICE). The border functions of the INS, which included the Border Patrol along with INS Inspectors, were combined with U.S. Customs Inspectors into the newly created U.S. Customs and Border Protection (CBP)."

The Immigration and Nationally Act of 1962, which is also known as McCarran-Walter Act controlled the immigrants that were entering the United States. The Immigration and Nationally Act usually were in charged of immigration and citizenship in the United States. Prior to the Immigration and Nationally Act were many laws regarding immigration but they weren't tied together in one single document. This Act in turn, gave solidity and unified all the naturalization and immigration laws. After the 9/11 immigration and nationally has gone through revisions "regarding the admissibility and removability of terrorist suspects has received much media and scholarly attention."

The Immigration Reform and Control Act (Simpson-Mazzoli Act) (IRCA) was an attempt to reduce illegal immigration to the United States which was currently seen as a threat to the U.S. economy. At the time the law was passed the immigrant population was largely illegal or unemployed. The law made hiring illegal immigrants a crime in an attempt to undermine the employment of illegal aliens. Similar to what is currently happening, in the 1980’s, the high number of illegal immigrants employed in low wage jobs and many other positions was seen as a “threat” to the ability of Americans to acquire jobs. While attempting to lower the number of illegal immigrants who would be hired, the legislature granted amnesty to people who had already been working and living in the United States. They proposed to allow regularization of status and eventually full citizenship. That decision was something non-synonymous with this eras attempt to lower illegal alien employment.
