Believe it or not one of the most frequently asked questions about visiting Hawaii is “Do I need a passport to visit Hawaii?” If you are a U.S. citizen or legal U.S. resident, you don’t need a passport.
Hawaii is one of the 50 United States and therefore a passport is not required for US citizens and legal residents. For example, if you lawfully reside in New York, you don’t need a passport to visit California or New Jersey, therefore you don’t need a passport to visit Hawaii.
In late 2015 and early 2016, news outlets have been reporting about the potential need for U.S. citizens to use a “Real ID” for domestic air travel. To date, a Real ID is not required. Read frequently asked questions regarding Real IDs on the Homeland Security website.
Though U.S. citizens and legal residents don’t need a passport to travel to Hawaii, a government-issued photo identification is required for adult travelers age 18 and older. A couple of examples of government-issued photo identification include driver’s license and passport. See this TSA link for other valid forms of identification.
If you are not a U.S. citizen or lawful U.S. resident, you are required to present a valid passport. For example, if you are a citizen of Australia and you visit Hawaii, you are required to present a valid Australian passport. Here’s what the U.S. Department of Homeland Security says:
All international visitors regardless of country of origin must present a passport or secure document when entering the United States by air.
