American colleges are still feeling the aftereffects of the September 11, 2001, terrorist attacks, particularly in areas like visa rules, international faculty exchanges, curriculum offerings, and campus risk-management and security planning, according to a report released this week by the National Association of Independent Colleges and Universities. International offices at colleges have developed new positions, channeled millions of dollars of financing, and devoted thousands of work hours to meet Sevis guidelines, according to college officials. In written comments accompanying their survey answers, respondents noted changes such as a shift in focus from programmatic and cross-cultural interests to compliance and data maintenance. Others said the processing of visas now occupies significantly more staff time.
