Donald Trump's administration proposed a new security mandate requiring travelers from Visa Waiver Program countries to submit extensive personal data, including five years of social media history, when applying for an ESTA.The CBP policy, published in the Federal Register, would make the submission of phone numbers, email addresses, biometric data, and close family details mandatory, affecting millions globally.Immigration experts like Farshad Owji criticized the measures, warning they could deter international travel, stifle free expression, and negatively impact tourism and the country's global image.
