Some law schools and colleges offer combined undergraduate and law programs, in which students can earn both the Bachelor's degree and the Juris Doctor degree in six years or less. These programs have less general study and offer fewer non-law curriculum choices. They tend to be offered less widely, though in several American institutions.
After you obtain the J.D., you need to take the bar exam in the state where you want to practice law. Each state sets its own rules for admissions to the state bar, but bar admission generally requires completing the law degree from an accredited law school and passing the bar exam. Depending on a country specific regulation of practicing law, individuals also might be required to undergo legal or training.
