In 2016, van Riemsdyk was named to Team USA once again for the World Cup of Hockey. He scored one assist in three games during the series, and the team was eliminated after losing its first three games in the preliminary round. He did not return to the international stage until the 2019 IIHF World Championship, where he put up two goals and three assists in eight games for Team USA. The United States team was defeated by Russia in a 4–3 quarterfinal matchup.
