At the start of 2006, Smith returned to the United States, where he began competing for New Wrestling Superstars. In August 2006, Smith began regularly wrestling for Fusion Pro Wrestling. He also wrestled for the American Wrestling Federation (AWF), and on November 11, 2006, he won the AWF Heavyweight Championship by defeating Steve Gatorwolf. In July 2007, he returned to the IWA in Puerto Rico, where he won the IWA World Heavyweight title for the second time by defeating Chicano on July 15. He later lost the Championship to Blitz on September 30, 2007. In October 2007, while touring Japan with Pro Wrestling Noah, he suffered a broken breastbone. In 2008, he returned to Pro Wrestling Noah, and, with Akitoshi Saito, won the GHC Tag Team Championship on May 23, by defeating Naomichi Marufuji and Takashi Sugiura. Smith and Saito also won the Global Tag League 2008. On April 14, 2010, Smith teamed up with Keith Walker to win the GHC Tag Team Championship from Takeshi Rikioh and Muhammad Yone.
