Aron Johannsson has been granted permission by FIFA to represent the USA national team.
The 22-year old American-born striker has represented Iceland at U21 level but has now changed allegiances to his nation of birth where he lived for just three years as a child before returning as a teenager.
AZ Alkmaar striker Johannsson has now been called up for Juergen Klinsmann's squad for Wednesday's friendly with Bosnia-Herzegovina in Sarajevo which has delighted both he and the national team boss.
"I'm super happy," said Johannsson. "When I came here, I didn't expect that I was going to be eligible to play. The coach told me right after training that the approval came through. I'm very excited."
Klinsmann added: "We are obviously very thrilled for Aron. It's an exciting time for him. He's done a great job in these couple days getting to know the guys. Hopefully if the game goes well tomorrow night, there will be a chance for him to make his debut with the US National Team."
