New York Red Bulls teenage forward Julian Hall said his international allegiance is "not solidified" despite earning his first U.S. men's national team call-up on Thursday. The 18-year-old was one of 13 newcomers named in coach Mauricio Pochettino's first roster since the United States' World Cup exit to Belgium.

Hall was born in New York City but holds dual U.S. and Polish citizenship, and has worn "Zakrzewski" on his jersey in a nod to his Polish mother. "I think it's definitely not solidified for me," Hall told The New York Post. "I appreciate the opportunity and I'm going to do as much as I can to make an impact, but I'm definitely still open to my Polish side. That's a side that I cherish a lot, especially because my mom is from there. I wouldn't say it's solidified."

Hall has represented the U.S. at U15 and U17 level but has also been called up to Poland youth camps. He could debut for the U.S. in friendlies against Peru, Chile, Canada and Mexico from Sept. 26 through Oct. 6. Even if he appears, he could still opt for Poland, as FIFA rules only commit a player after a competitive game.

After debuting in 2023, Hall has nine goals and five assists in 25 MLS appearances. Red Bulls teammate Adri Mehmeti also earned his first call-up.
