Pro bono activities

  • Usman provides pro bono representation to an Afghani family of six who was separated when fleeing the volatile conditions following the U.S. military’s 2021 withdrawal from Afghanistan. Alongside other Fish attorneys and partner organizations, Usman advocated for his clients’ asylum status with government embassies in multiple countries, including working with the U.S. embassy in Ukraine, where the family had been settled just prior to the Russian invasion. The team’s efforts culminated in the family’s eventual reunification and safe arrival in the U.S.
