Family immigration is one of the main ways of legal entry into the U.S. and getting permanent residence in this country. The main condition for an immigrant visa to be granted is having relatives - USA citizens or permanent U.S. residents (Green Card holders) ready to fully sponsor your living in the USA. The U.S. citizen or permanent residents (Green Card holders) must file a Petition for Alien Relative and prove that he has enough assets to support you.

Immigrant visas to the U.S. are the visas allowing foreigners to immigrate to the U.S. for the purpose of residence and employment without restrictions existing for holders of non-immigrant visas.
Immigrants are essential to keeping the American economy strong and, in industries from fast food to high tech, they fill an intrinsic need in the labor force. Several classes of business immigration visas allow workers, with skills in demand by U.S. employers, to be admitted to the United States to work on a temporary or permanent basis.

The United States often signs treaties with other countries in order to promote trade and investment, which in turn encourages peaceful and mutually prosperous relations. Recently the U.S. has signed several Bilateral Investment Treaties with mainly former communist states, which were intended to foster investment but generally did not confer immigration privileges. Individuals or companies in countries involved in such treaties can apply for visas to work in the USA in order to build and manage their investment in and trade with the U.S. This class of visas is called E visas.
