The purpose of a Certificate of Citizenship is to prove the holder’s identity as a U.S. citizen. The certificate is issued by the government to individuals who are derivative citizens and those who acquired citizenship. This differs from a naturalized citizen who took affirmative steps to become a U.S. citizen and went through the process of naturalization. Those individuals will receive a Certificate of Naturalization. Derivative citizenship is citizenship transferred to the child(ren) of naturalized U.S. citizens, or in some cases, to foreign-born children adopted by parents who are U.S. citizens. Acquired citizenship is citizenship bestowed at birth on a child born overseas to a U.S. citizen mother and/or father.
Who is Eligible?
Derivative Citizenship Under certain circumstances, a child can derive U.S. citizenship through his or her parent(s) who has become a naturalized U.S. citizen. The exact requirements vary depending on when the parent naturalized, however, the basic requirements for being eligible for derivative citizenship include the following.
  • Have at least one parent who is a U.S. citizen
  • Be physically in the legal custody of a U.S. citizen parent
  • Have a green card
  • Be less than 18-years old
  • Be unmarried
  • Be the legitimate child of a U.S. citizen, or a legitimate relationship was established prior to the child’s 16th birthday (not a stepchild)
  • If adopted, satisfy the requirements of section 101(b)(1)(E) or (F), the adoption must be full and finalized, and one of the following must be applicable:
    • The U.S. citizen parent has resided a minimum of 5 years in the U.S., at least 2 of those being after the parent’s 14th birthday, or
    • If the U.S. citizen parent cannot satisfy those requirements, the child must have a grandparent who:
      • Is a United States citizen, and
      • Has resided for a minimum of 5 years in the U.S., at least 2 of those being after the grandparent’s 14th birthday, and
      • Is alive at the time of the adjudication of the application and the child’s Oath ceremony

She was perfect! It was such a luck to have Julia Greenberg referred to me by my acquaintance. She is the most caring and helpful attorney I have ever worked with. She is very professional and knowledgeable in the immigration law, and she gave me great advice! I appreciate most that she is always available by phone or returns missed calls shortly – this is something that many attorneys in NYC do not do or have their assistants do who never give the correct answer. I approached Julia to help me prepare for my citizenship interview since I had, frankly speaking, not an easy case, and she did the best  job I could expect. I could not imagine how my interview would have gone without her; her support was significant! If I ever have a question about any immigration matter I would definitely ask Julia for help again. Awesome

Julia is very professional, competent and knows how to get the best deal for her clients. What we appreciated about her service was that she always answered our calls or got back to us in a very short amount of time. We had a very stressful issue with the officer but Julia was able resolve it and have our case successfully processed the same day. We could have not done it without her. She is a smart lawyer and a great negotiator with a wonderful personality. Hire Julia Greenberg if you want to get a real result!
