Insanely, submitting your past 5 years' social media to enter the U.S. as a tourist is only a small part of the proposed upcoming requirements. You'll also need to give your DNA (!) among many other new requirements. All the additional info you'll need to give as a tourist eligible for ESTA (meaning those tourists who don't need a visa, for instance from EU, UK, Australia, Japan, and other Visa Waiver countries): - All social media accounts from the last 5 years - All your biometrics: face, fingerprint, DNA, and iris - All your phone numbers from the last 5 years - All your email addresses from the last 10 years - IP addresses and metadata from your submitted photos - Names of your family members (parents, spouse, siblings, children) - All your family members' phone numbers from the last 5 years - Your family members' dates of birth - Your family members' places of birth - Your family members' residencies - All your business phone numbers from the last 5 years - All your business email addresses from the last 10 years If you do need a visa (i.e. non ESTA), I imagine the requirements are going to be far more drastic. This is straight from the Department of Homeland Security documentation which you can find here:

Surprised by the amount of people replying who think their "private" info on social media is actually private. So public service announcement: if you're a non-US citizen, nothing is private. US law, like Section 702 of the Foreign Intelligence Surveillance Act (FISA), stipulates that US authorities can ask to see anything and social media companies are required to give it. They don't even need a warrant or probable cause (and they obviously don't need your passwords).
