She started in all seven matches for the United States in the 2015 tournament, and she played every minute of all six United States matches at the 2011 FIFA Women's World Cup. In 2012, Krieger sustained a serious knee injury during the 2012 CONCACAF Women's Olympic Qualifying tournament and did not recover in time to be selected for the 2012 Olympic Team. After fully recuperating, Krieger was named to her first Olympic team four years later and participated in the 2016 Rio Olympics. She became the oldest first-time US Olympian for women's soccer.
Before joining Gotham FC in 2022, Krieger played professional soccer for the Washington Freedom, FFC Frankfurt of Germany's Frauen-Bundesliga, Tyresö FF of Sweden's Damallsvenskan, Washington Spirit, and Orlando Pride.
