Citizenship encompasses an entire body of law inside the vast realm of immigration. The ever changing laws relating to citizenship and naturalization can be extremely complex and esoteric. In addition to claims for U.S. citizenship based on acquisition at birth to one or both U.S. citizen parents, it is important to be able to spot issues of derivative citizenship, including through naturalization of one or both parents, availability of expedited citizenship for children predicated on having a citizen parent and relying on physical presence of a U.S. citizen grandparent, and special citizenship provisions based on U.S. military service. If your family history reveals one or more of these issues, you should consult with an immigration attorney to help resolve any complex citizenship questions.
