The United States government has reinforced restrictions under its Visa Waiver Programme (VWP), making certain travellers from participating countries ineligible to enter the country without first obtaining a visa.
The updated measures are being enforced under the Visa Waiver Program Improvement and Terrorist Travel Prevention Act, a law introduced to strengthen border security and enhance the screening of international travellers.
According to the US Department of State, the restrictions affect citizens of countries that participate in the Visa Waiver Programme who have travelled to, or been present in, North Korea, Iran, Iraq, Libya, Somalia, Sudan, Syria, or Yemen on or after March 1, 2011. The policy also applies to travellers who have visited Cuba on or after January 12, 2021.
Individuals who fall into these categories can no longer use the Electronic System for Travel Authorization (ESTA), the online platform that allows eligible travellers to enter the United States for short stays without obtaining a visa.
The tightened rules also apply to people who hold dual nationality with any of the listed countries. Regardless of their primary citizenship, dual nationals are permanently ineligible to travel under the Visa Waiver Programme and must instead apply for a traditional US visa through a US embassy or consulate before travelling.
While the policy does not prohibit affected individuals from entering the United States, it changes the process they must follow. Instead of enjoying visa-free access under the VWP, they are required to complete the standard visa application process, which includes submitting an application, attending an interview where required, and undergoing additional security checks.

US authorities say the measures are aimed at addressing national security concerns by ensuring more comprehensive vetting of travellers who may have connections to regions identified as presenting heightened security risks.
The Visa Waiver Programme currently allows eligible citizens from participating countries to travel to the United States for tourism or business for stays of up to 90 days without obtaining a visa. However, travellers affected by the latest restrictions will no longer qualify for this privilege and must obtain the appropriate visa before departure.
The US Department of State has advised travellers to confirm their eligibility before making travel arrangements and encouraged those affected by the restrictions to begin the visa application process well ahead of their intended travel dates to avoid delays.
