A bid is being made to secure talks with the home secretary over the loss of funding for three police officers at ferry ports in south west Scotland.
The move by the UK Border Agency last month affected sites at Stranraer and Cairnryan.
Dumfries and Galloway Council now wants to persuade Theresa May to meet a cross-party delegation of councillors and politicians in London.
It has concerns the ports could be targeted by criminals or terror groups.
The UK Borders Agency has said it has a more "substantial resource" in Northern Ireland which is more "conveniently located" to carry out checks on passengers crossing the Irish Sea.
However, councillor Archie Dryburgh, of the authority's police committee, said the need for further talks about the issue remained.
He said checks that commercial vehicles were not being used to conceal illegal immigrants required a police presence.
"We need police officers there to deal with that side of things," he said.
"We need to keep this thing going and ensure that the government understands how deeply we feel about our police in the ports in Stranraer and Cairnryan."
