The U.S. government is planning to require foreign tourists to disclose up to five years of their social media activity prior to entering the country. This sweeping new policy, primarily under consideration by the Trump administration, aims to intensify checks on visitors, including those from countries participating in the visa waiver program such as the UK, Australia, Germany, and Japan. Travelers may face mandatory inspections of their social media histories, leading to potential implications for millions of tourists planning to visit the U.S. Additionally, these measures could result in stricter vetting processes for tourists, raising concerns about privacy and civil liberties.
