Each summer, the Winant and Clayton Volunteer program sends a group of Americans to volunteer in London for seven weeks and provides housing and a small stipend to help defray the high cost of living. After seven weeks of volunteering, participants have two weeks to travel independently to other places before returning to London to evaluate the program and get their flight back to the United States. The application includes a few short essays, a series of questions about the type of placement one would prefer, and an informal interview with former volunteers that gives applicants a chance to find out more about the program. Deciding to participate takes a small leap of faith. The roster of volunteer placements and housing options can change from year to year and volunteers can’t choose their placement in advance. But once you’re accepted you instantly feel that you’ve joined a close-knit group. The volunteer coordinator is in frequent contact through mailings and e-mails to help you prepare for the trip, and there is a daylong orientation in New York that brings all the volunteers together before departure for London.
