The bipartisan border deal struck by top appropriators in both chambers is slated to come to the House floor for a vote on Thursday evening, though the final time is still to be determined.
The agreement provides $1.375 billion to build 55 miles for a barrier along the southern border, the amount included in the fiscal 2018 bill.
The legislation — which is needed to avert a second partial government shutdown ahead of Friday's deadline — is expected to narrowly pass the lower chamber.

"I think they lose 40-50 votes," one GOP lawmaker told The Hill.
The deal received mixed reviews from the House Republican conference.
"It's a good deal; it's not a great deal.

"And there's a lot of give and take on something like that."
Granger told The Hill it's "the first year of a multiyear plan to do the wall," adding the president is "going to find the rest of the money for his wall" using other tactics.
Conservatives have balked at the agreement for falling far below the $5.7 billion requested by the administration to build a wall along the southern border.
