Vice President Biden is heading to New Hampshire ... in an official capacity.

The potential 2016 presidential candidate -- who has made little secret of his designs on running -- will go to Nashua, N.H., on March 25.

The event will focus on "workforce development and the value of on-the-job training opportunities," according to the White House.

A White House aide said Biden will visit the state with Labor Secretary Thomas Perez.

While the event will be in an official capacity, it will likely be viewed as something of a debut for Biden on the eve of the 2016 Democratic primary.

But it won't be the first time the vice president has found himself on the radar in one of the early primary states. Biden had been slated to raise money for New Hampshire Gov. Maggie Hassan (D) in August (he had to cancel due to family reasons). He also visited Iowa for Sen. Tom Harkin's (D-Iowa) annual Steak Fry fundraiser and South Carolina for the state Democratic Party's Jefferson-Jackson Dinner.
