Hundreds of colleges and universities around the country did not meet Friday's deadline to register all international students in a new government database, prompting worries among Bay Area school administrators that some students would be turned away at airports.

Officials at some local schools scrambled through Thursday night to put the names and addresses of students into the Student and Exchange Visitor Information System that was created after it was revealed that some Sept. 11 hijackers held student visas.

``Do we feel good about it? No. Is it a fun thing? No,'' said Helen Stevens, director of international programs and services at San Jose State University, where 1,400 of its 30,000 students are on visas to study in the United States. ``It's all consuming.''

San Jose State, Stanford and Santa Clara universities are among 241 educational institutions in the Bay Area that met Friday's deadline, according to the Bureau of Immigration and Customs Enforcement. The agency did not disclose how many of the nation's 600 schools that did not meet the deadline are in the Bay Area. About 6,000 schools across the country are now certified to have met the deadline.

There were no reports of international students denied entry at San Francisco International Airport on Friday. But some Bay Area school administrators, at the request of immigration officials, were on standby via telephone all day, bracing for calls from airport immigration inspectors.

``Everything is going well,'' said Chris Bentley, an immigration bureau spokesman. ``We took an antiquated, paper-driven system and now we have a computerized system that can be accessed in real time.''

The agency Friday dispatched agents to seven major U.S. airports, including San Francisco, where 70 percent of all international students enter. The agents were on hand alongside immigration inspectors to review and resolve problem cases.

Now when students arrive at a U.S. port of entry, an immigration inspector will review their documents and check whether their names appear in the database, which now contains data on 1.3 million international students in the U.S., Bentley said.

Government agents are making special accommodations for students who might have been mistakenly left out of the database or students whose schools are still working to input the information, Bentley said. In both cases, immigration inspectors will call school officials on the spot and verify a student's documents.

``We haven't had any calls,'' said Ted Goode, director of Services for International Students and Scholars at the University of California-Berkeley.

Goode said that he and his staff completed the data entry of about 2,500 foreign students Thursday afternoon. In April, Goode and other education officials around the country reported pervasive and major technical problems with the database. Documents were printed in error, the system generated mistakes and it lost data.

``One of our fears is that we will in fact misinterpret or miscommunicate something that will do harm to a student,'' Goode said.

Sarah McGregor, director of the English language program at San Jose State, met 25 arriving college students from Tokyo on Friday morning at San Francisco International Airport.

``The kids said the lines were long but there were no problems with the inspectors,'' she said.

Arriving summer students from Asia said the immigration inspection was relatively hassle-free.

``It was very simple, but I had a difficult time understanding because of my limited English,'' said Kensuke Ohta, 20, a student from Sophia University in Tokyo, who is going to study English at Santa Clara University.
