Scheme expected to open in November
Undocumented migrants will have a chance to regularise their legal status, which is being called a "once in generation" amnesty.
Junior Minister with Responsibility for Law Reform, James Browne has said he would not refer to the scheme as amnesty, as there would still be strict criteria in place.
This would include migrants living in the Republic for at least 4 years, or 3 years in the case of children.
The scheme will be brought to Cabinet next month.
The portal is expected to open towards the end of November.
Deputy Browne tried to abate fears, saying it is a safe scheme, and undocumented people can "come out of the shadows".
He joined Clem Ryan on this morning's edition of 'Kildare Today':
