Yes. Malaysian citizens require a valid U.S. visa to enter Hawaii (a U.S. state), regardless of stay duration. They must apply at the U.S. Embassy in Kuala Lumpur. Visa type depends on purpose: B-1/B-2 (tourism/business), F-1 (student), H-1B (work), etc. The Visa Waiver Program (ESTA) does not apply to Malaysia.
