The US Embassy in Dublin says it is working to resolve issues some students applying for a J-1 visa are facing.
Under new rules to the popular working holiday programme, this year applicants are required to provide evidence of a pre-arranged job in the US.
However, a number of students are reported to have experienced issues with programme sponsors - with some applicants saying they have had to postpone or cancel their travel plans as a result.
The US Embassy here says it is aware of issues in processing applications for 'dozens' of Irish students.
The Embassy says the problems are affecting some of those who have applied through Irish company Travel Bug Limited and their independent US programme sponsor, American Work Adventures.
In a statement, the Embassy says: "We are engaging with a number of independent US sponsors to ensure that affected Irish students who are eligible and qualified to participate in the J-1 program this year have every opportunity to do so".
It adds that any students facing last-minute processing delays can collect their passports from the Embassy in Ballsbridge within two working days after their scheduled interviews.
