The national government policy that controls and oversees the phenomenon and procedures relating to the immigration of their country is referred to as the Immigration Law or in other words we can say that, residency of non-citizens is subject to rules and regulations put forward by a law known as the Immigration law. The International Organization for Migration specified that there are more than 200 million migrants around the world todayImmigration law with regard to foreign citizens is related to the nationality law, which usually governs the legal status of the population in matters like citizenship. Immigration laws differ from one country to another, and also according to the political climate of the period, as sentiments might sway from the widely inclusive to the deeply exclusive. Immigration law concerning the citizens of a country is regulated by international law. Some countries maintain stern laws which regulate both the right of entry and internal rights, such as the time span of their settlement and the right to take part in government dealings. Immigrants who seek to reside permanently in U.S. need to be fully aware of the terms and conditions mentioned in their visa category and take personal accountability in maintaining lawful status and rules.
The immigration laws are essential components in respect to immigration and emigration of people travelling to and fro from country. Immigration law became a serious political issue in the USA, particularly after the 9/11 incident that occurred in the year 2001. As an aspect of economic policy, immigration can be considered as a necessary evil for filling specific gaps in manpower, or dynamic force for economic expansion. Since the early 1960s, immigration as an issue of public interest, exclusively meant immigration by non-whites from the Caribbean, Africa and Asia. The politics of immigration is also being linked to issues, like national security, terrorism, and in Western Europe especially, with the rise of Islam as a new major religion. Because of such issues, immigration has become an intense emotional and political issue in some European countries.The five major departments of the federal government that takes care of the immigration process are the Department of Homeland Security, the Department of State, the Department of Labor, the Department of Justice, and the Department of Health and Human Services. It is further divided into three distinctive departments: US Citizenship and Immigration Services, Immigration and Customs Enforcement, and Customs and Border Protection. The United States allows more than 1 million migrants to become Legal Permanent Residents every year, which exceeds the number in any other country in the world. Some countries, such as Japan, have set their immigration laws in a way to prevent immigrants from entering and residing within, the country.
Non compliance with these regulations can result in the failure of a foreign national to gain entrance to the United States and also potentially hamper a company’s ability to do business in the country. Immigrants are different from tourists because tourists don’t move from one country to another for economic purposes. With the passage of time the concept of immigration has changed to some extent and has been related to the development of nation-states and nationality law.
