The US senate is expected to start debating a compromise bill on immigration reform tomorrow.
There are fears that the new legislation would permanently exclude Irish immigrants from the opportunities offered to earlier Irish immigrants.
The President for the Irish Lobby for Immigration Reform has said this is the last and best chance for an estimated 50,000 undocumented Irish in the US to get legalised.
Speaking on 'This Week', Grant Lally said there is much support for Irish people in the United States to become legal.
