The midfielder moved to the Bundesliga after becoming a standout with the New York Red Bulls after breaking through at age 17.
He's made five Bundesliga appearances for the club, and has proven more than capable by stepping straight into a consistent role in the midfield.
RB Leipzig haven't lost any of the five matches in which Adams has appeared, including Monday's 1-1 draw with Hoffenheim.
Adams came off the bench at halftime and helped set up Willie Orban's 88th-minute equalizing goal.
"It's such a great league in general and you see so many young players able to develop in such an amazing league," Adams told Bundesliga.com after the match.
"It was such a great decision to come to a club like this that players young players and wants to develop them.
"I am eager to get more games and continue to develop."
Adams earned his U.S. national team debut in November 2017 and rapidly became one of the core pieces of the midfield, scoring his first international goal against Mexico last September.
He was not a part of the annual January camp, the first under new head coach Gregg Berhalter, as he completed his move and began play with RB Leipzig.
