U.S. has denied visas to a team of six Afghan teenage girls who want to showcase their handcrafted ball-sorting robot at the FIRST Global Challenge, an international robotics competition held in Washington DC this month. No reason was given. A similar team from Gambia met the same fate in April. Makes no sense since teams from "Muslim-ban countries" Iraq, Iran and Sudan will be at the competition. When young women show dedication and capability, they should be given the avenue to inspire others.
