Prior to immigrating to the United States, it is important for people to understand the laws about federal, state and local income taxes and to know the requirements about registering for the Selective Service, explains U.S. Citizenship and Immigration Services. It is also crucial to understand the civil liberties that govern life within the country, including those that pertain to social discrimination, employment, medical care, families and security, states the Criminal Justice Degrees Guide.
In the United States, it is imperative that workers file income tax returns and report any earned income to the Internal Revenue Service, explains U.S. Citizenship and Immigration Services. The same information must be provided to the state, city and local tax departments in some areas. If a person does not file taxes or claims to be a non-immigrant on tax returns, the government may relinquish a person's citizenship status.
All men in the United States between the ages of 18 and 26 must register with the Selective Service, states U.S. Citizenship and Immigration Services. When applying for immigration, this may automatically take place, but it is up to individuals to ensure this happens. Although the United States currently does not have a military draft, signing up for the Selective Service states that you are of an age to participate if mandatory.
