  • If any one of your parents or both your parents have been naturalized

It might seem surprising, but many people have attained US citizenship without even realizing it. These people are usually grouped into three categories, which are:

  • The first one is people born in the US but have lived outside of the country most of their lives. Some of these people mistakenly believe that they may lose their citizenship and Naturalization by living outside of the country for an extended period, but this isn't the case
  • People who believe they are not citizens even if their ancestors were US citizens. It could be that an individual was born outside of the US that person is a citizen if their parents or grandparents were US citizens
