The list is set to be announced on Monday.
Foreign Affairs Minister Simon Coveney has said that the USA will not be on the travel 'green list', while it's unlikely that the UK will be included either.
The Government is set to publish the list of countries deemed safe to travel to on Monday.
People arriving from green list countries won't be required to self-quarantine for 14-days when they arrive in Ireland.
Speaking to The Pat Kenny Show, Mr Coveney explained: "This is not on the basis of politics - it's on the basis of epidemiological data and numbers, so we can compare Ireland to other countries.
"Then we can put people on a green list that we regard as representing no higher risk than Ireland represents.
"In other words, travelling to one of these countries wouldn't be any different to travelling to Kerry, Connemara or Donegal for your holidays."
When asked whether the US will be one of the countries on the list, he responded emphatically, saying there's "no question" that will be the case.
He said: "I think it's very unlikely our closest neighbour either (The UK) will be under that threshold that we set.
"That's really unfortunate, because the two countries we would like to be opening up to in terms of international travel are the UK and US, given the integration between our economy and those two countries."
When it comes to selecting which countries will be included on the list, he said the government will be looking at data such as number of cases per 100,000 people.
