Available literature showed that the Egyptian diaspora (e.g., emigrants who share a common situations and work for the same cause) has been developing and engaging politically in the United States during the 2011 Egyptian revolution. The diasporas’ role was of interest to researchers and policymakers; however, the literature concerning diasporas has underexamined the Egyptian diaspora regarding its proliferation and active political engagement. Using the conflict and climate theories of Truman, and Cigler and Loomis in conjunction with the political engagement factors theory of Jang as the theoretical foundation of the study, the purpose was to explore how members of the diaspora explain and perceive their political engagement in Washington, DC. In this qualitative study, the key characteristics of diaspora and political and social factors of home and host countries that enable and inhibit that engagement regarding particular issues were addressed through 16 in-depth, face-to-face interviews with Egyptian-Americans. Maxwell and Miller’s doubled-strategy and Yin’s case study steps approach were used for analysis. The findings indicated that the engagement of the diaspora except Coptic and some Islamic groups are passive most of the time because of the political home culture; despite that fact, the diaspora became active for a short time because of the Egyptian revolution. Future research should exam those aspects to better understand the mechanism of building an Egyptian lobby to work continuously and effectively on Egyptian interests in the United States. The diaspora and policymakers may use the study results to help improve the role of this diaspora to impose positive social changes in Egypt and the future political engagement of Egyptian younger generations.
