Ndiaye is the director of the Mauritanian Network for Human Rights.

Alongside urging policymakers to grant Temporary Protected Status to Mauritanian migrants like Siley, he provides hands-on support by hosting five Mauritanian newcomers in his family's home.

Despite the skyrocketing utility bills, Ndiaye is steadfast in his support, “I can't just leave them on the street or in jail,” he says. When they called, he opened his door, even though he had never met any of them before.
