Admission to the bar in the United States is the granting of permission by a particular court system to a lawyer to practice law in the jurisdiction and before those courts. Each U.S. state and similar jurisdiction (e.g. territories under federal control) has its own court system and sets its own rules for bar admission, which can lead to different admission standards among states. In most cases, a person is "admitted" or "called" to the bar of the highest court in the jurisdiction and is thereby authorized to practice law in the jurisdiction. Federal courts, although often overlapping in admission standards with states, set their own requirements for practice in each of those courts.
