The Arsenal striker, who is on loan at French Ligue 1 side Reims this season, was born in the US to Nigerian parents but moved to England at the age of two.
As such he was eligible to represent Nigeria, US and England, whom he played youth football for.
The 21-year-old scored seven goals in 13 appearances for the England u-21 side but has chosen to represent the country of his birth.
“My decision to represent the United States came together with my family,” Balogun said.
“In the end it became a no-brainer, but for sure it’s just something I wanted to do and it feels like I’m at home here. To represent the United States means a lot, more than people would know.
“I’m very proud and honoured to have this opportunity, and I want to give everything I have to make our team successful.”
“We are delighted that Folarin has chosen to represent the United States,” USMNT head coach Anthony Hudson said.
“Not only is he an extremely talented player, he’s also a good man who is going to add value to our national team both on and off the field at a time when the team is continuing to improve. It’s clear that he values his U.S. roots and we can’t wait for him to come in and be a part of the team.”
Balogun has scored 19 goals in 34 Ligue 1 matches this season.
