The term immigration basically stands for the travel by citizens of one country to another country as well as the legal processes and requirements involved. Immigration is an important part of any democracy. It enables citizens acquire the necessary documents and permission to travel overseas to other nations for whatever reason.

There are plenty of reasons that people need to travel. People may travel overseas to pursue their careers or job opportunities; they may travel for holidays, medical treatment or even to study. Others travel to visit family or move away in search of a better life or to escape from persecution of one form or another.

There are quite a number of reasons why people need to migrate and governments have the responsibility of facilitating this process and ensuring that it is conducted in a fair, just and legal manner. It should be conducted in a manner that benefits the host country and not hurt its citizens, but provide benefits. There are plenty of benefits that immigration can bring forth. These include benefits from tourism, an enhanced workforce that includes skilled and professional workforce, a cosmopolitan and diversified population that seeks to integrate people from all works of life so they have shared interests, beliefs and values.

In Australia, immigration is managed by the department of immigration and citizenship. This department is headed by a cabinet minister who is in charge of policy. The civil servants or government employees oversee the everyday running and management of the department. They manage Australia’s borders, entry points and also issue visas to visitors intending to enter the country. Australian law requires that every non-citizen entering the country requires a visa. Only Australian citizens may enter the country without a visa. The department is charged with the responsibility of issuing visas to foreign nationals seeking to enter Australia.

Australia missions overseas provide a vital service to Australians and foreign nationals alike, in matters of immigration. If an Australian citizen has family in another country, the immigration department can assist in getting them together, and help them move or travel to Australia.

European nations have a close knit immigration system that has policies which operate within the entire EU region. A good example is the Schengen visa. This is a visa that is issued by one E country but allows its holder travel and stay through out the 25 EU nations that are signatories to the Schengen treaty. The EU immigration policy also allows citizens of the entire region to live and work in any of the member nations within the EU, with little or no restrictions.

The US government has an immigration policy that allows foreign nationals from certain countries visa free entry into the US. These countries include nations from the EU, Korea, Australia, Canada, Japan, New Zealand, Singapore and a few others. The rest of the world will need a visa to enter the USA.

Immigration is a very important aspect of any modern nation. However, the policies and principles guiding this vital sector should not be used to keep out innocent, hard working, good citizens of the world, but should aim at keeping out unwanted persons such as criminals and terrorists.
