In 2001, Tahirih launched the Campaign to Prevent Abuse and Exploitation through the International Marriage Broker (IMB) Industry to address the abuse of so-called "mail-order brides". Alongside law firm Arnold & Porter Kaye Scholer, Tahirih successfully litigated "Fox v. Encounters International" in 2004, a case that marked the first time in the United States that an IMB had been held liable for negligent conduct that put a woman at serious risk in an abusive relationship and kept her in danger by misleading her as to her legal options.
