In 1996 there were allegations of prejudicial treatment of Asian Americans in uniform in World War II. Congress directed Louis Caldera, then Secretary of the Army, to conduct a full review of military records. The review concluded that 22 Asian Americans, including Wai, did not receive full consideration for the Medal of Honor. In 2000 Wai's Distinguished Service Cross was upgraded to the Medal of Honor. Of those whose medals were upgraded, Wai was one of only two who did not belong to the predominantly Japanese American 442nd Regimental Combat Team/100th Infantry Battalion; the other being Rudolph B. Davila of the 7th Infantry. At a White House ceremony June 20, 2000, President Bill Clinton presented the Medal of Honor to 22 Asian Americans whose Distinguished Service Crosses were upgraded to the Medal of Honor.
