International career
Born in the United States, Cremaschi was born to Argentine parents and is thus eligible to represent either country.[8] He was called up to the United States under-19s for their winning campaign at the Slovenia Nations Cup in September 2022.[9] In October of the same year, he was called up to a training camp for the United States under-20s to prepare for the 2023 FIFA U-20 World Cup.[10]
On August 30, 2023, Cremaschi got called up to the USMNT 2023 September games, along with his teammate Drake Callender.[12] On September 13, 2023, he made his debut for the USMNT, coming on a substitute in the 71st minute in a friendly match against Oman.
On July 8, 2024, Cremaschi was selected as the youngest member of the United States men's Olympic soccer team for the 2024 Summer Olympics in Paris, where the group stage opponents will include France, New Zealand, and Guinea on July 24, 27, and 30th, respectively. Since 1992, the Olympic mens soccer competition is contested not by the senior national teams but rather by the U23 teams, of which the 18 members must include at least 15 players under age 23 as of January 1 of the Olympic year. At most 3 overage players can be added to each country's U23 Olympic squad. As the only member of the current US Olympic selection who was born in 2005, Cremaschi is the sole player who will remain U23 age-eligible for the 2028 Summer Olympics to be held in Los Angeles.[14]
