On Tuesday, March 19, INS Commissioner James Ziglar appeared before Congress to respond to questions about the recent approval notices issued in the cases of the two men who flew the planes into the World Trade Center on September 11. In his testimony, Mr. Ziglar stated that INS is considering regulatory changes that would result in most holders of visitors' visas being admitted for a period of 30 days, rather than the current practice of admitting visitors for 180 days. According to the Commissioner, INS is also considering changes to regulations that would prevent a person who has entered under some other status from beginning a course of study before their request for a change of status to student is approved.
