The House May 8 approved HR3525, a bill that would increase the force guarding U.S. borders and require foreign visitors to carry tamperproof passports and visas, AP reported.

The bill, which President Bush is expected to sign, boosts border patrol agent pay and allows the Immigration and Naturalization Service to hire 200 new investigators and 200 new inspectors.

The measure also requires the INS to set up a foreign student tracking system. In addition, visitors must carry documents that can be read by machine, identifying the bearer using face recognition or retinal scanning technology.
