You can attend a Hawaii college at the in-state tuition rate without being a Hawaii resident if you are stationed here, are using VA education benefits, or are using the Gunnery Sergeant John David Fry Scholarship. Your authorized dependents get the resident rate too.
Apply for residency classification for tuition purposes through the admissions or residency office of the Hawaii school you are attending, and give them your orders or VA education benefit paperwork.
Your orders showing you are stationed in Hawaii or in a Hawaii-based unit, or your VA Certificate of Eligibility for the education benefit you are using, plus proof of your relationship to the service member if you are a dependent.
