The video-sharing app, owned by Chinese company ByteDance, is accused of posing a national security risk through data gathered from millions of users.
A request for a change in ownership, first reported in the Wall Street Journal (WSJ), was confirmed to BBC News by TikTok.
The company said a forced sale would not change its data flows or access.
The White House has not yet responded to a BBC News request for comment.
For years American officials have raised concerns that data from the popular app could fall into the hands of the Chinese government.
