Section 62.8 - General program requirements(a)Size of program. A sponsor, other than a federal government agency, must have no fewer than five actively participating exchange visitors during the annual reporting cycle (e.g., academic, calendar or fiscal year), as stated in its letter of designation or redesignation. The Department of State may, in its sole discretion, waive this requirement.(b)Minimum duration of program. A sponsor, other than a federal government agency, must provide each exchange visitor, except those sponsored in the short-term scholar category, with a minimum period of participation in the United States of no less than three weeks.(c)Reciprocity. In conducting its exchange visitor program, sponsors must make a good faith effort to develop and implement, to the fullest extent possible, reciprocal exchanges of persons.(d)Cross-cultural activities. In addition to category specific requirements, sponsors must:(1) Offer or make available to exchange visitors and the accompanying spouses and dependents, if any, a variety of appropriate cross-cultural activities. The extent and type of the cross-cultural activities will be determined by the needs and interests of the particular category of exchange visitor. Sponsors will be responsible for determining the appropriate types and numbers of such cross-cultural programs, unless otherwise specified by the Department. The Department of State encourages sponsors to give their exchange visitors the broadest exposure to American society, culture and institutions; and(2) Encourage exchange visitors to participate voluntarily in activities that are for the purpose of sharing the language, culture, or history of their home country with Americans, provided such activities do not delay the completion of the exchange visitors' program. 79 FR 60307 , Oct. 6, 2014
