I know a lot of people who stay 2 or 3 months in the winter and they do not leave or get a extension. I am a resident but my Daughter is not. She stays 3 months at a time. Sometimes when she leaves, the say you might want to get a extension the next time you come back but they don't enforce it much. The thing is in Aruba, you can line up 10 Arubans and ask them the same question and you will get 10 different answers. That's Aruba!!!
