Border ID Test Run Creates Long Delays for Travelers
United States border agents have stepped up scrutiny of Americans returning home from Mexico, slowing commerce and creating delays at border crossings not seen since the months after the Sept. 11 attacks. The increased enforcement is in part a dress rehearsal for new rules, scheduled to take effect in January, that will require Americans to show a passport or other proof of citizenship to enter the United States. The requirements were approved by Congress as part of antiterrorism legislation in 2004.
