Giousouf was born on 5 May 1978 in Leverkusen to ethnic Turkish Gastarbeiter parents, who immigrated in the 1970s from Greece, where they lived as a minority in Western Thrace.

The members of her immigrant family spoke Turkish as well as Greek at home as their native languages, denoting their ethnic ancestry and original nationality, as well as German; they are naturalised and second-generation citizens.

[4] With fashionable ponytails, hipster horn-rimmed glasses, and dressed in black Cemile Giousouf looks like the CDU as a whole would be like to be seen: urban, contemporary, elegant.

Giousouf, who was 24th on the state list of the CDU NRW and a direct candidate in the constituency Hagen – Ennepe-Ruhr-Kreis I, did not make it into the 19th German Bundestag.

This appointment was criticised in some quarters as Giousouf had "close contact" with "Turkish nationalists ('Grey Wolves'), Islamists (Millî Görüş) and Erdogan supporters (UETD)".
