US citizens have been cautioned that certain behavior could now be considered illegal after major legal updates took effect at a popular Asian travel hub.
Travelers from the United States may be required to provide access to their phones, laptops, and the passwords connected to those devices if requested while visiting this part of Asia.
Under newly updated national security provisions, declining to hand over passwords or provide decryption help for personal electronics can be treated as a criminal offense.
The U.S. Consulate General said the revised measures are being implemented in Hong Kong and Macao, following amendments to rules tied to the National Security Law framework.
This week, authorities in Hong Kong expanded police powers, including broader access to individuals’ digital devices.
The U.S. Consulate General Hong Kong addressed the development in a March 26 press release and urged U.S. citizens to be aware of what has changed.
The statement read: “On March 23, 2026, the Hong Kong government changed the implementing rules relating to the National Security Law.
“It is now a criminal offense to refuse to give the Hong Kong police the passwords or decryption assistance to access all personal electronic devices including cellphones and laptops.
“This legal change applies to everyone, including U.S. citizens, in Hong Kong, arriving or just transiting Hong Kong International Airport. In addition, the Hong Kong government also has more authority to take and keep any personal devices, as evidence, that they claim are linked to national security offenses.”
As for what to do if impacted, U.S. citizens were advised to contact the U.S. Consulate General in Hong Kong or Macau if they are arrested or detained.
The consulate also recommended following the State Department’s Bureau of Consular Affairs on social media for updates that could include new guidance or travel disruptions.
In addition, travelers were encouraged to enroll in the Smart Traveler Enrollment Program (STEP) to receive alerts and security-related notifications.
The advisory did not specify how often police are expected to use these expanded powers, nor did it outline how requests for access may play out on the ground.
Separately, the issue of device searches has drawn attention elsewhere as well. In 2025, U.S. Customs and Border Protection highlighted broad authority to inspect travelers’ electronic devices, raising concerns among some people seeking entry into the United States.
That scope can include phones and laptops at U.S. ports of entry under what is commonly referred to as the border search exception.
However, under U.S. law, refusing to provide a password is not, by itself, a criminal offense.
