Speaking to Sport Bild, Culbreath confirmed there is no contact with the US Soccer Federation at present. The 18-year-old said he does not expect to be called up by the Americans and is instead focused on helping Germany's under-19 side reach the European Championship. His immediate priority, he said, is the U19 Euros campaign with the DFB rather than any senior question at this stage.
The winger holds dual citizenship through his American father and was born in Landstuhl, near Kaiserslautern. He represented the United States at under-16 level in November 2022 but has since appeared exclusively in the German youth system, earning caps from U16 through to U19. He has made 32 appearances for Germany's youth teams in total.
Culbreath broke into the Bayer Leverkusen first team in December 2025, scoring on his Bundesliga debut as a substitute in a 3-1 win at RB Leipzig. He has since become a regular presence in Kasper Hjulmand's squad, starting in back-to-back league fixtures and impressing in a 1-1 draw with Bayern Munich in March. Hjulmand has praised his development consistently, describing his recent progress as excellent while noting that work is ongoing to develop the defensive side of his game. Culbreath signed his first professional contract with Leverkusen in January, committing to the club until 2030.
The timing of the nationality question is notable. With the 2026 FIFA World Cup on home soil approaching, the United States would benefit from adding a talent of Culbreath's profile to their pool, and his eligibility remains intact. But Culbreath was careful not to commit either way. Asked about the future, he said only that he does not know what it holds.
Germany's senior head coach Julian Nagelsmann has not been drawn publicly on whether Culbreath features in his thinking.
