What are the visa & residency requirements in Hawaii?

"The process of applying for a visa to visit or stay in Hawaii depends largely on the individual's current citizenship or residency status. Generally, most visitors to Hawaii require either a valid visa or an approved ESTA (Electronic System for Travel Authorization). Those from visa waiver countries can travel without additional requirements provided they comply with ESTA requirements, while those from non-visa waiver countries are expected to obtain a visa from a U.S. consulate prior to their visit. The process of becoming a legal resident of Hawaii requires a more comprehensive process, including obtaining an appropriate visa prior to travel, such as an immigrant visa, and then submitting a variety of documents to U.S. Citizenship and Immigration Services to apply for a Green Card. Once approved, an individual will then be eligible to live and work in Hawaii indefinitely. They must initially maintain Green Card status by staying in the state for at least 6 months of the year, and then apply for permanent residency through a process of naturalization after having lived there for five years," wrote a member who made the move to Hawaii.
