A new US proposal might force foreign visitors to hand over way more personal data than before.

The plan targets visa waiver applications from 42 nations—think UK, Spain, France, Japan, and others. What's on the list? Every email address you've used in the past decade. Plus five years' worth of additional records.

This isn't just paperwork creep. It's a glimpse into how border control keeps expanding its digital reach. Privacy advocates won't like this one bit. For travelers from those countries, get ready to dig through old inboxes and account histories before your next trip stateside.

The proposal's still under review, but if it goes through, expect longer application forms and a whole new level of data surveillance at entry points.
