Q: I am a US naturalized citizen father and my biological child has a US passport can my child lose citizenship?

A: If your child acquired U.S. citizenship through the Child Citizenship Act of 2000, it's important to understand that once citizenship is granted, it is not easily lost, even if living abroad for an extended period. The possession of a U.S. passport is a strong indication of citizenship, and not having a Certificate of Citizenship does not negate the citizenship status. Your child's citizenship remains valid even if the passport expires while abroad.

Should your child's passport expire while you are living outside the United States, your child does not lose U.S. citizenship. However, traveling back to the U.S. or any other country would require a valid passport. In such a scenario, you would need to apply for a new U.S. passport for your child at a U.S. embassy or consulate in the country where you are residing.

Regarding the renewal of your child's passport, it is generally possible for one parent to apply for a child's passport renewal, provided you have the required documentation and parental consent. If the other parent is not available, you may need to provide additional documentation explaining why their consent cannot be obtained. It's recommended to check the specific requirements with the nearest U.S. embassy or consulate. Your concern about the financial aspects of obtaining a Certificate of Citizenship is understandable, but rest assured, the passport serves as proof of citizenship for your child.

A: Your child will not lose his/her citizenship if you live abroad for a long time with your child. If your child passport expires, it will not be considered having lost citizenship. You can renew the passport of your child at the US embassy while living abroad. This would avoid any issues when your child travels back to the U.S. I suggest you take a look at the required documentation for renewal of US passport at the US embassy or Consulate in Mexico.
