The Highland League outfit face a play-off with Edinburgh City, with the winner playing the bottom-placed team in League Two.
But Brora have expressed concern over the financial implications of travelling further distances and getting players out of work to play matches.
Brora say they have done all they can to avoid the play-off but have been told they must play the Lowland League winners.
The winners of the tie will take on the team that finish bottom of League Division Two which is currently Montrose.
Brora President John Young said: “We’ve looked at all options and there’s no way we can avoid competing. We meet SPFL criteria for entry level so we can’t opt out.
“My personal thoughts are that I’d rather we stay where we are but as a club we have to move forward and we will be trying our best to get through into the SPFL.
“Our players are professional and they always want to win every game.”
