The purported intent of the bill, originally introduced by Sens. Barbara Boxer (a California Democrat) and Roy Blount (a Missouri Republican) at the behest of American Israel Political Action Committee (AIPAC), is to provide Israel entry into the United States' visa waiver program, but with special allowances not afforded any other country. Normally, the visa waiver program permits, under certain conditions, foreign individuals to enter the United States without a visa. A key aspect of the program is reciprocity, meaning that countries admitted into this program must also permit Americans to enter their country without a visa. Currently, 37 countries participate in this mutually beneficial arrangement with the United States. All reciprocate by allowing American citizens to cross their borders without obtaining visas.
