Senators Tim Johnson (D-SD) and Norm Coleman (R-MN) introduced legislation yesterday to increase the tax deduction for families who host international exchange students from $50 to $200 per month. The Youth Exchange Support Act of 2007, S. 2252, would index the deduction to inflation for future years. Originally set in the 1960s to encourage families to host foreign exchange students, the current $50 tax deduction has never been increased.
