Antarctic immigration laws are as generous as can be while maintaining provisions for national safety. Specifically, before any non-citizen, tourist or otherwise, is allowed off the boats into Antarctica, they must first pass a background check to make sure they are not likely to cause violence, and then receive a resident identity card. After that, they are free to stay as long as they like, unless they commit crimes or cause violence, in which case they can be removed from the country. After four years of good behavior, non-citizen residents are eligible for naturalization, in which they receive a citizen identity card and become full Antarctic citizens. Additionally, people born anywhere to at least one Antarctic citizen, or born in Antarctica to at least one lawful resident or citizen, automatically become citizens, and underage citizens, whether born or naturalized, receive identity cards once they turn 15. For its humanist values and its kind, friendly, and fair-minded citizens, Antarctica always has been and continues to be a destination for people from all walks of life and all around the world.
