The FIF said they had full confidence in Wahi and he was not travelling for Saturday's match in Toronto because authorisations for his travel to Canada had not been obtained.
French authorities said unusual betting patterns were detected around a yellow card Wahi received in a Ligue 1 match while playing for Nice last month.
"To date, the FIF has not been officially notified of any legal or administrative proceedings concerning him," the FIF said in a statement.
"During this particularly difficult period, the FIF offers its full support to the player and reaffirms its confidence in him. Elye Wahi remains an important member of the Ivory Coast national team.
"The player will not be able to join the delegation’s trip to Canada. This is because the administrative authorisations required for him to enter Canadian territory have not yet been obtained. Elye Wahi will therefore remain in the United States until the team returns."
Ivory Coast beat Ecuador 1-0 in their first Group E match, while Germany are coming off a thumping 7-1 win over Curacao.
