An application for a visa card for a British passport has been put on hold amid concerns it may be too complicated to complete.
Barclay Visas have been used in the EU since 2005, and were introduced to the UK for non-EU nationals aged 18 and over.
They can be used by both British nationals and EU nationals.
The application process has been suspended while the EU and UK carry out further investigations into the issue, the British embassy in Dublin has said.
The visa card is not required by law in Ireland, but applicants have had to fill in an application form, which they must fax to the embassy.
The embassy says it will look at whether the visa card was valid or not, but it is unlikely that would be possible without the assistance of a solicitor.
It is not clear if the suspension will affect the number of applications made by British nationals or EU nationals who wish to apply.
If you are applying for a UK visa, we recommend you contact the British Embassy in Dublin (08) 8485 3113.
