Immigration law is said to refer to the national government polices that control the phenomenon of immigration to their country.
According to foreign citizens, immigration law is related to the nationality law, which governs the legal status of the people in matters, such as citizenship. Immigration law is said to vary from one country to another as well as to the political climate of that time.
The international law regulates the immigration law regarding the citizens of a country. All the country/countries are allowed entries to its own citizens through the United Nations International Covenant on Civil and Political Rights.
Strict laws, which regulated the right of entry and internal rights, once were maintained by certain countries. This included the duration of stay and the right to participate in the government. Many countries have laws that show a process for naturalization by which immigrants may become citizens.
The immigration law is found to be used in various ways in different countries whereby, in the UK, immigration law states that the British Overseas Citizens have identical legal rights to the British citizens distinguished only in the title. Anybody born in Britain or a British overseas territory has the right to obtain British citizenship. This is also available as a right for people of whom one parent is a British or British overseas citizen otherwise than by descent.
EU citizens, as created by the Treaty of Rome, Article 17, have the right to work, provide services or select self-employment in the UK.
The immigration law in the US is a very serious political issue as the nation heads for the 2008 presidential elections. Due to the backlog in the processing of the immigration applications by the United States Citizenship and the immigration Services (USCIS), many are still waiting to become citizens of the US.
A lot of countries have their own control measures set up at the entry points to the country (e.g., airports and roads near the border) where a traveller’s documents are checked. The documents required are passports with or without visa, a WHO vaccination card, tickets, and, at times, a presentation of the amount of cash one is carrying.
