The Bush administration would require commercial airlines and cruise-line operators to collect information such as fingerprints from international travelers and send the information to the Homeland Security Department soon after the travelers leave the country, according to a proposed rule.

The proposal, which will be announced Tuesday, will close a security gap identified after the 9/11 attacks and identify which visitors have overstayed their visas.
