After earning 15 caps between 2013 and 2014, Mewis fell off the national team radar. Following a 5 year absence, she was called back up to a USWNT talent identification training camp in December 2019 by new coach Vlatko Andonovski.[34] She was called to the full senior team training camps in both October and November 2020 prior to a friendly against the Netherlands. Mewis came on as a second half substitute against the Netherlands, marking her first appearance in over six years, and scoring in the 70th minute.
