The US government may soon require tourists from dozens of countries to submit their social media history for the past five years before entering the country. This comes as part of a new proposal by US Customs and Border Protection and the Department of Homeland Security. The rule will affect travelers who enter the US under the Electronic System for Travel Authorization (ESTA), which allows visa-free visits of up to 90 days. Countries affected include the UK, France, Australia, Japan, and others. The proposal asks for social media information, phone numbers from the past five years, and email addresses from the last 10 years. It also seeks more details about applicants' family members. This move follows tougher border security policies initiated by President Donald Trump, citing national security reasons. The administration has previously required visa applicants like students and skilled workers to make social media accounts public. The new policy is part of efforts to prevent entry by people who may support terrorism or violence. Critics, like the Electronic Frontier Foundation, warn this could harm civil liberties. Immigration lawyers say processing times for applications might increase. This policy could affect US tourism, which is expecting big events like the World Cup and 2028 Olympics. The public can comment on this proposal for 60 days. Meanwhile, other Trump administration policies have impacted tourism, including a travel ban on 19 countries and a drop in Canadian visitors, who traditionally make up a large portion of foreign travelers to the US.
