Efforts are underway in the US to try to secure senate approval for a bill that could give Irish workers access to thousands of US visas every year.
Last week, the US House of Representatives voted in favour of adding Ireland to the E-3 visa programme, which is currently only available to Australians.
The proposal needs unanimous support in the US Senate before it can become law.
Six Republican senators had put a hold on the bill but three of them have now agreed to support it, meaning three senators remain undecided.
Efforts are under way to try to convince them to lift their hold so that the matter can proceed to a senate vote.
