On April 12, 2021, President Joe Biden announced his intent to nominate Jaddou to be the director of the United States Citizenship and Immigration Services.[3] On April 15, 2021, her nomination was sent to the Senate.[9] The Senate confirmed her on July 30, 2021 by a 47–34 vote.[10]
Leadership of USCIS
Under Jaddou, USCIS changed its mission statement in February 2022 to include words like "welcome" and "respect" for immigrants, after the Trump administration moved to emphasize that the agency's work included "securing the homeland."[11] The Trump administration also had removed the phrase, "nation of immigrants," from the agency's mission statement, prompting backlash from immigrant rights groups, but Jaddou did not restore the phrase.
Jaddou has called for USCIS to hire thousands of additional staff to address record case backlogs. She testified in Congress in April 2022 that the agency was still dealing with vacancies and morale problems experienced during the Trump administration.[12]
