Just about every country in the world has its own migrants policies and laws. Migrants laws refer to the national government policies which control the phenomenon of immigration to their country. These laws vary from country to country and depend after prevailing personal conditions in the country which sway for and against the favor of new immigrants.
Migration laws of a country are regulated by The United Nations International Agreement on Civil and Personal Rights which states that all the countries allow entry to its own citizens. The international migrants laws come into action when someone applies for a passport, travels from his native country to another country or tries to enter another country for employment or education.
