B-1 Visitor for Business is a visa classification that can be used by international visitors making a short visit to UCD. B-1 visitors are not eligible for employment in the United States and are not eligible to apply for a Social Security number.
Visitors from countries participating in the visa waiver program are eligible for the W-B Business Visitor status. In general, the same rules apply to the W-B as apply to the B-1. However, a significant difference is that individuals requesting W-B status, who enter the U.S. without a B-1 visa stamp in their passport, can only stay in the U.S. for a maximum of 90 days and cannot extend their stay or change their status inside the U.S.
