Many US elected officials, both Republicans and Democrats, believe that the popular video platform, owned by the Chinese group Bytedance, allows Beijing to access users' confidential data.
They have introduced several bills in recent weeks to ban the app, which has more than 150 million users in the United States.
Several TikTok influencers traveled to the US capital this week to vehemently oppose the ban.
"We're in Washington, you see the Capitol right there," says the tiktokeuse @countrylather2020, in a video with the hashtag #keeptiktok (#gardeztiktok).
"We hope to talk to a few senators," says the woman whose account specializes in making soaps.
"Hi everyone, I'm just outside Lindsey Graham's office in the U.S. Senate," greeting card designer @sparksofjoyco said in another video about an influential Republican elected official.
"I will be in contact with them to make them understand the impact that TikTok has on my life and my business and all the concerns you have shared in the comments," she promises her more than 90,000 followers.
The boss of the application, Shou Chew, will be heard by US elected officials on Thursday.
