The people from all over the world are free to move to any part of the world and settle down there permanently. A person may be born anywhere in the world, but he has a legal right to move any part of the world according to his or her choice or preference. It is important to note that the people who are looking for moving from one place to another needs to get the official permission for them to settle down any part of the world. They can also get the citizenship of the place to which the people are intending to move. As a matter of fact, the shifting process from the original country to another country and settle down there is a very complicate one.

This is one of the most complicated processing ever seen or experienced by the people. Technically, this shifting from one country to another is termed as immigration. Today, as the entire world has been severely affected by greater incidents of disturbances, so the countries are also paying a very close attention towards these incidents. This shifting is termed as Immigration and it is very important for the person to the official permission or 'No Objection Certificate' from the native place and nation of the applicant.

However, the role of the receiving nations is equally important and that is these countries also follow a great processing for the immigration applications. The situation in the United States of America is equally serious as it is the most powerful nation in the world and quite naturally, it always remains in the target of the terrorists and separatists who always look for ways of doing some harm to the USA. These Immigration laws were first introduced as federal laws and they were very strict by nature as they are held responsible for all types of processing.

Initially, the applications of Immigration in the USA were processed by the various agencies and services that were given the responsibility to verify the validity of the application forms. Till very recently, the processing of the Immigration applications were processed by different agencies and authorities. However, after the incidents of 9/11, these immigration laws in the United States of America have been made extremely strict and that is why they can be very authentic and they must allow really deserving people to settle down in the United States of America.

At present, the applications for immigration in the United States of America are processed by Department of Homeland security. This is the most authentic body of specially appointed people whose responsibilities include looking after all the technical aspects of Immigration in the USA. Certainly the task is not easy and that is why the Department of Homeland securities are divided into three different agencies that work independently and are responsible towards the Department of Homeland Securities. These three agencies under the Department of Homeland Securities are U.S. Customs and Border Enforcement (CBE), U.S. Citizenship and Immigration Services (USCIS) and U.S. Immigration and Customs Enforcement (ICE). These agencies work independently. However, all these three agencies work in close cooperation of one another to ensure the best processing of Immigration applications to the United States of America.
