Khan was a society hostess in Washington while her husband was the Persian chargé d'affaires there. "I find that few Americans, even traveled and cultured ones, know Persian as it deserves to be appreciated," she told an interviewer in 1910. The Khan family greeted Bahá'i leader ‘Abdu’l-Bahá on his arrival in Washington in 1912, and hosted a luncheon for him, with guests including Louis Gregory. She contributed Persian recipes to "The Economy Administration Cookbook" (1913). In 1914, she and her husband attended the Panama-Pacific International Exposition in San Francisco, representing Persia. She was an occasional lecturer on Persia to community groups.
