Certificate of Citizenship (Form N-600)
Confirming citizenship that already exists by law
Not everyone needs to go through naturalization to become a U.S. citizen. In some cases, individuals may already be citizens through their parents, even if they were born outside the United States.
Form N-600 allows eligible individuals to obtain a Certificate of Citizenship, which serves as official legal proof of their status.
Who may qualify
Citizenship through Form N-600 may apply to individuals who:
-
Acquired citizenship at birth through a U.S. citizen parent
-
Derived citizenship automatically after a parent naturalized
-
Meet specific legal and residency requirements established by law
These cases often require a detailed legal analysis to determine eligibility.
Why documentation is critical
Unlike naturalization, these cases are not about applying for citizenship — they are about proving that citizenship already exists. This means that documentation must clearly establish:
-
The parent’s citizenship status
-
The relationship between parent and child
-
Physical presence requirements
-
Legal custody and residency, when applicable
Common challenges
These cases can become complex when:
-
Records are incomplete or unavailable
-
There are gaps in residency history
-
Citizenship laws changed over time
-
Family structures are not straightforward
Our approach
We carefully evaluate each case to determine eligibility and build a strong evidentiary record. Our goal is to ensure that the application clearly supports the claim to citizenship and avoids unnecessary delays.
