Egypt does allow dual citizenship,
The Embassy of Egypt's website is http://www.mfa.gov.eg.not in English ;
DUAL NATIONALITY: In addition to being subject to all Egyptian laws affecting U.S. citizens, dual nationals may also be subject to other laws that impose special obligations on Egyptian citizens. #The Government of Egypt considers all children born to Egyptian fathers to be Egyptian citizens. #
Even if the children bear American passports, immigration officials may require proof that the father approves their departure before the children will be allowed to leave Egypt. Americans married to Egyptians do not need their spouse's permission to depart Egypt as long as they have a valid Egyptian visa. To renew a visa, or to leave the country after a visa has expired, an American woman married to an Egyptian must present proof of her husband's consent. If a dual national resides in Egypt for extended periods, proof of Egyptian citizenship, such as a family I.D. card, is required. Male dual nationals who have not completed military service are not generally required to enlist in the armed forces. However, they must obtain an exemption certificate through the Ministry of Defense Draft Office before they can leave Egypt. Individuals who may be affected can inquire at an Egyptian consular office abroad before traveling to Egypt. Dual Egyptian-American nationals may enter and leave Egypt on their U.S. passports. Persons with dual nationality who travel to Egypt on their Egyptian passports are normally treated as Egyptian citizens by the local government. The ability to provide U.S. consular assistance to such persons, therefore, is extremely limited. For additional information, please see our Dual Nationality flyer on the Consular Affairs home page on the Internet at http://travel.state.gov/.
