Citizenship Through Parents
(N-600)
You May Already Be a U.S. Citizen
Some individuals are already U.S. citizens through a parent but are unaware or do not yet have proof of citizenship.
If you were born outside the United States to a U.S. citizen parent, you may have automatically acquired or derived U.S. citizenship. Determining eligibility can be confusing, especially when laws vary based on dates, residency, and parental status.
At Lex Migration, we help individuals understand whether they may already be U.S. citizens and guide them through the N-600 process with clarity and care.

What Is Citizenship Through Parents (Form N-600)?
Form N-600 is used to apply for a Certificate of Citizenship for individuals who are already U.S. citizens through a parent.
Eligibility depends on several factors, including:
- Whether one or both parents are U.S. citizens
- Where and when you were born
- Your parent’s physical presence in the U.S.
- Whether you lived with or were in the custody of the U.S. citizen parent
Because citizenship laws can change over time, careful review is essential.
