In 1983, U.S. Soccer entered the United States national team, as Team America, into the NASL. The team drew on American citizens playing in the NASL, Major Indoor Soccer League and American Soccer League. However, both the USSF and the NASL quickly discovered that many top American players preferred to remain with their existing clubs. In order to fill the roster, U.S. Soccer was forced to draw on foreign imports, and it negotiated with the Earthquakes to loan Green to Team America, despite the fact that he was still a British subject. Team America's 1983 season was a disaster, with a league-worst 10–20 record and dwindling attendance figures; the club folded at season's end. Green then became a free agent and signed with the New York Cosmos as the team prepared for the 1983-84 NASL indoor season. Green received his American citizenship in November 1983, and played with the Cosmos through the indoor season, the subsequent 1984 outdoor season, and finally the club's 1984-85 indoor season in the Major Indoor Soccer League. In 1985, just as the NASL was collapsing, Green retired as a player.
