Sepp Blatter says FIFA will not comment on this week's allegations concerning Qatar's successful World Cup bid.
A newspaper report claimed the FBI is looking into payments allegedly made to former FIFA vice-president Jack Warner by a Qatari firm linked to the 2022 campaign.
That has not been verified by the FBI, who told Sky Sports News they are prohibited by law from confirming or denying any investigation.
Warner has dismissed the report as "foolishness" and claims there is a "witch-hunt" against the Qatar campaign.
FIFA president Blatter, speaking at the organisation's conference in Zurich, said: "This problem is now dealt with by an independent party. Let them deal with it, and once dealt with we can have this dialogue."
In the meantime FIFA's own investigator Michael Garcia has been busy interviewing committee members as part of his ongoing inquiry into the bidding processes for the 2018 and 2022 tournaments.
Russia won the first of those campaigns, beating England among other rivals, and Prime Minister David Cameron this week cast doubt on the integrity of the process.
He said: "All I can tell you is there are a lot of people who promised they were going to vote for me. And in the end, I think we got one vote."
