Federal Immigration law is a complex area that is meant to manage such questions as who an alien is, who can become a US citizen and who should be rejected, how and when a person can enter the country and much more. The law is multifaceted and it is based on international treaties, administrative procedures and codes.
The USA is considered to be the nation of immigrants; more and more people are migrating to this country every day. The migration started long ago, people from India, China, Italy, France, Spain and other countries come here with the hope to become US citizens. There was no Immigration law in the US for a long time, but when the waves of migrating people became larger and larger, the need of such a law became stronger.
First of all, the law helps to check the people entering the country; it is crucial that the people coming to the US are not dangerous for the US citizens; moreover, the country follows certain policy. The thing is that the US Immigration Policy seeks to admit workers with certain skills to take the positions that are vacant. This will foster the economic growth of the country and increase the standard of living.
However, the main goal of the US Immigration Policy is to reunite families. If you are a US citizen and you want your immediate relative to live next to you in the same country, then it will be quite easy for them to use the Immigration law and to settle in the US. Things will be more difficult with more distant relatives. For example, if you are an adult citizen of US, it will be rather difficult for your brothers or sisters to become citizens of the country. On the other hand; unmarried children are given the most preference.
As it has been said above the US Immigration law is a complex phenomena and it comprises several other laws and regulations. Congress is the only body that has got the greatest power over immigration issues. The president deals only with the cases of refugees. As for the states, they have their own limitations concerning the immigrants; however, they do not have the power to enact any immigration laws.
The Immigration and Nationality Act (INA) is a central part of the US Immigration law, it includes different regulations that manage the immigration to the country. Different agencies aim to implement the INA.
In 2003 the INS (Immigration and Naturalization Service) which was an agency the duty of which was to enforce the US Immigration law was replaced by the Department of Homeland Security (DHS).
Immigration laws may seem complicated for commons citizens, so if you want to study, work or live in the USA, you had better turn to an experienced immigration lawyer who will be able to guide you through the whole process of migration.
