Every year, around 20,000 young women and men come to the United States as au pairs to care for children, learn about American culture and improve their English. The cultural exchange program is organized by the federal government and is especially popular among families who need flexible childcare at an affordable rate.

Host families pay a sponsoring agency $8,000 upfront and the au pair a $195.75 weekly stipend, room and board and a $500 education credit. In return, the au pair can work up to 45 hours per week. When all the funds are counted, au pairs are left with $4.35 per hour in their pockets.
