Non-US citizens and permanent residents may import the following duty-free:
- 1L of liquor (if you're over 21 years old)
- 200 cigarettes (one carton) or 100 non-Cuban cigars (if you're over 18)
- $100 worth of gifts
Hawaii has stringent restrictions against importing any fresh fruits and plants. Because Hawaii is a rabies-free state, the pet quarantine laws are draconian.
Before leaving Hawaii, make sure any fresh flowers or produce has been commercially packaged and approved for travel (else you'll be forced to surrender those pineapples at the airport).
Generally not required for Canadians or for citizens of Visa Waiver Program countries for stays of 90 days or less with ESTA pre-approval.
Double-check current visa and passport requirements before coming to the USA. See the 'Visas' section of the US Department of State website (http://travel.state.gov) and the Travel section of the US Customs & Border Protection website (www.cbp.gov).
Currently under the US Visa Waiver Program (VWP) visas are not required for citizens of 37 countries for stays up to 90 days (no extensions) if they register online at least 72 hours before arrival with the Electronic System for Travel Authorization, which costs $14. Canadian visitors are generally admitted visa-free for stays up to 182 days.
Upon arrival, the Department of Homeland Security (www.dhs.gov) requires that almost all foreign visitors (currently excluding most Canadian citizens) have their digital photograph taken and electronic (inkless) fingerprints scanned; the process typically takes less than a minute.
