Minister for Foreign Affairs Micheál Martin has begun a three-day visit to the US.

The Minister will discuss immigration reform with political representatives from both houses of the US Congress in Washington later today.

He will once again mark out Ireland's position on the 'undocumented' or those who are in the US illegally.

Immigration reform is an important issue for the Irish Government, but the US Congress is now involved in a major battle over healthcare reform.

President Barack Obama has committed his administration to deal with the issue in the early part of next year.

The Minister is also anxious to eventually get the best deal possible for Irish people who want to go to work in the US in the future.

They are hoping for something along the lines of a two-year renewable work visa, which is similar to one that is in operation between Ireland and Australia.
