How to obtain the US citizenship and an American passport

Have you considered obtaining the US citizenship?

The United States is a nation that identifies itself and connects through the values of freedom, justice and equality that its citizens share.

Many of these citizens are immigrants who helped to shape the country with their rich contributions. Naturalized citizens are a fundamental part of the U.S. and the decision to become a U.S. citizen offers many equally important benefits and responsibilities.

By becoming a citizen, you are reaffirming your commitment and loyalty to the country that offers the best professional and personal opportunities in the world.

There are different ways to obtain the American citizenship: 

  • Being the son of an American citizen;
  • By being a legal permanent resident for 5 years;
  • Marrying an American citizen;
  • Serve in the US Armed Forces.

Citizenship through American parents

There are two ways to obtain US citizenship through American citizen parents: at birth and after birth, but before the age of 18. Congress enacted laws that determine how citizenship is passed on by an American citizen parent (or parents) to children born outside the United States. The law in force at the time of birth determines whether someone born outside of the United States, the child of a parent (or parents), an American citizen, is an American citizen at birth. In sum, these laws require that at least one parent be an American citizen and that the American citizen parent has lived in the United States for a period of time.

Citizenship for legal permanent residents for 5 years

This is the most common way for a foreigner to become an American citizen. The applicant must demonstrate that he has been a permanent resident legally admitted to the United States for at least five years.

Citizenship through marriage to an American citizen  

To be eligible for naturalization, you must be at least 18 years old, be a permanent resident legally admitted to the United States for at least three years, and have lived in conjugal union with your American spouse for the three years immediately preceding the date on which you filed your claim. 

Citizenship through military servisse 

If you are serving or have served in the U.S. armed forces, you may be eligible to apply for naturalization under the special provisions of the Immigration and Nationality Act.
