President Barack Obama plans to survey damage from the Washington state mudslide later this month and will meet victims, first responders and recovery workers, the White House said.
The White House said it plans to release further details about the president's trip to Oso, Washington, in the coming days.
Mr Obama spoke with Representative Suzan DelBene on Tuesday about the recovery effort.
"He called to say that he's going to come out to visit the site on April 22," she said.
They discussed ongoing assistance from the Federal Emergency Management Agency as the area copes with the slide that has killed at least 34 people, destroyed about three dozen homes, partially dammed a river and covered a state highway.
One more person was added to the victims list on Tuesday by the Snohomish County medical examiner's office, which is still trying to identify four of the dead.
A dozen people remain on the sheriff's list of missing from the March 22 slide that buried homes along the North Fork of the Stillaguamish River about 55 miles (90 kilometres) north east of Seattle.
