The Ulster Unionist Party may shut down its Washington office because of its collapse in popularity in Northern Ireland.
The party is currently deciding whether to keep a representative in the US after the party was left with only one MP following the British general election.
It has been represented in the US for the last 10 years by Scottish woman Anne Smith-Porter and last year held its first fundraiser in New York. Ms Smith-Porter said no decision had yet been reached, but said the office was likely to stay open until the end of June, when the party's quarterly expenditure on its Washington operation runs out.
The party does not have to pay any rent in Washington, courtesy of Ms Smith-Porter's employer, Tony Cullen Foster, a businessman originally from the North.
Ms Smith-Porter said that as the UUP now only had one MP, there was a sudden loss in income for the party.
She also said that she had not heard of any DUP plans to open a US office.
The party uses its Washington base as a platform to counter Sinn Féin, which has a much larger presence in the US and collects hundreds of thousands of dollars every year.
The SDLP has long talked about setting up a US office. Deputy leader and newly elected MP Alasdair McDowell has long been a supporter of the move.
