What are the requirements for obtaining a Certificate of Citizenship?

You can obtain a certificate of citizenship if you fall into one of the following categories.

  • US Citizenship through Birth

Any child born in the US automatically acquires US citizenship, even if the child's mother was in the US illegally. Unless the child was born to a foreign diplomat at the time of birth.

  • US Citizenship through Parents

Even though a child is born outside the US, the child can automatically acquire US citizenship if at least one parent was a US citizen at the time of the child's birth.

  • US Citizenship through Adoption

Children under 18 years of age holding green cards may be naturalized if petitioned for by a US citizen parent.

  • US Citizenship Retention

Individuals born and raised outside the US, being unaware of having acquired US citizenship through their parents or grandparents and have therefore failed to fulfill US residency requirements may claim US citizenship through the Doctrine of Constructive Retention.
