He’s not going to be the belle of the ball.

Mayor Eric Adams’ visit to Washington DC to press migrant issues this week will not include a sit down with President Biden — and simply involves an invitation at a White House-run holiday party with “countess” other local officials, The Post has learned.

Hizzoner is set to head to the nation’s capital on Thursday as part of his latest trip to lobby the federal government to provide more help to deal with the ballooning cost of the crush of asylum seekers in New York City.

While City Hall has released few details about the visit, the Post has learned that his only contact with the White House is his invitation to a party thrown by the administration for numerous local leaders. It’s not clear if Biden will even be there.

“Mayor Adams was invited to the White House Intergovernmental Affairs Holiday Reception, as were countless other officials from across the country,” a White House spokesperson told The Post.

“We have nothing to preview at this time regarding a meeting with the President,” the spokesperson said, adding that the Biden admin has been ” team is “in constant communication with Governor Hochul and Mayor Adams’ teams.”

Adams has ramped up his criticism of the feds over their handling of the migrants since the summer and has conceded that he hasn’t spoken to Biden this year. Adams previously touted his close ties to the president and dubbed himself the “Biden of Brooklyn.”

Adams told reporters Tuesday his administration has reached out to the White House for a meeting along with any other agency that could help with the crisis but a spokesperson said the mayor’s schedule would not be released until Wednesday evening.

Adams last landed a closed-door meeting with Tom Perez, the director of intergovernmental affairs, in August.

Gov. Kathy Hochul, on the other hand, has met with White House Chief of Staff Jeff Zients twice over the last few months to address the crisis.

Thursday’s trip will be the mayor’s 10th trip down to DC to try to lobby the feds for more support with the more than 150,000 asylum seekers who have come through NYC since the start of the crisis, which is expected to cost $12 billion.

The feds meanwhile have provided some staffing to help with paperwork but only carved out less than $150 million.

City Hall didn’t immediately return a request for comment.
