North Korean defectors are North Korean people who left North Korea to become citizens in a new country. In North Korea, it is against the law to leave North Korea without permission. North Koreans are also not allowed to change their own citizenship, so anyone born a North Korean must also die a North Korean. The punishment for leaving North Korea without permission is extremely harsh. People who are caught are usually sent a prison camp or put to death in public. Like many other crimes in North Korea, illegally leaving the country may not only punish the accused, but also his or her family up to three generations.
