Legal Question in Immigration Law in New Jersey

Hello - please call me at (212) 968-8600. Kind regards, RDM

It depends on how the person obtained U.S. citizenship, i.e., whether they derived citizenship through a parent or applied for citizenship via the naturalization process. Assuming you are referring to someone who applied for citizenship via naturalization, you can find the date of citizenship on their naturalization certificate. If the person derived citizenship from a parent, then it's a bit more complicated and I would need more information to help you. If you wish to follow up with me to discuss this matter further, contact me at [email protected]. I don't charge for consultations.
