Enlisted Marine Corps ranks are broken down into three levels, Junior Enlisted, Non-Commissioned Officers, and Staff Non-Commissioned Officers. As a Marine moves up the ladder his or her responsibility and contribution to the mission increases.
Also, children born abroad to two non-citizen nationals or to one alien parent and one non-citizen national parent are eligible for non-citizen national status. This is so rare that the State Department does not even issue a certificate for it. Non-citizen nationals are delineated as such in their passports.
Nearly 7 million U.S. passports are issued every year. Only the U.S. Department of State has the authority to issue United States passports and only U.S. citizens have the right to apply for a U.S. passport. If you are not a U.S. citizen you first need to apply for United States citizenship. A valid US passport may be used to enter most foreign countries. U.S. citizens may now apply for the new U.S. Passport Card and hold both a regular passport and passport card. Some U.S. citizens hold dual citizenship, which means that an individual holds another citizenship besides U.S. citizenship.
