U.S. Customs and Border Protection has entered a new proposal into the federal register asking travelers to reveal their online presence. The proposal would add a new field in which foreign visitors can declare their Twitter handle. The new field would be added to the Electronic System for Travel Authorisation (ESTA) and Form I-94 that is used as a record to notify United States authorities in advance of their arrival to and departure from the country. The public has 60 days to write to the agency’s Washington, D.C. office before the proposal is formally considered.
