Minister for Justice Helen McEntee is expected to inform Cabinet colleagues that she intends to add Egypt, India and Brazil to the State's list of safe countries.
It means that asylum seekers from the these nations will have their International Protection applications dealt with within three months.
Minister McEntee is expected to bring a list with a total of five countries to Cabinet tomorrow.
It comes as the topic of immigration has moved up the agenda as a concern for the public in opinion polls.
The Government believes that as it takes more steps to deal with accommodation for those seeking International Protection, it also needs to examine its immigration processes.
The designation of a state as a "safe country" of origin does not mean that a person cannot apply for international protection.
However, it places an onus on the applicant to demonstrate why, and by way of exception, they are in need of protection.
It means that asylum applicants from the countries will be subject to accelerated processing, and will have their cases considered, and decisions issued within a maximum of 90 days.
Safe countries of origin are those where it can be shown that that there is generally and consistently no persecution, no torture or inhuman or degrading treatment, and no threat by reason of indiscriminate violence.
Nick Henderson, of the Irish Refugee Council said that the legal test for designating a country as safe "is high".
He said: "There must be no inhuman or degrading treatment, persecution or internal conflict.
"When we considered the country of origin evidence for each country, and applied it to that test, we don't think they can be designated as safe.
"A country that is perceived to be safe is not safe for everyone.
"While refugee recognition rates from these countries may generally be lower than average, there is evidence that some groups, such as women, members of the LGBTQI+ community, religious minorities, indigenous peoples and other vulnerable people are routinely persecuted."
Ten countries on list
There are currently ten countries on Ireland's list, which began in November 2022.
They are Albania, Algeria, Bosnia and Herzegovina, Botswana, Georgia, Kosovo, North Macedonia, Montenegro, Serbia, and South Africa.
The Department of Justice has said that the introduction of accelerated processing has had a "significant" impact on the number of applications from those countries, which have dropped by over 50% since the measure was introduced.
Figures from the Department of Integration show that as of 23 June, most applications for international protection were from Nigeria (6,230).
Nigeria is followed by Georgia (3,510) and Algeria (3,026) - both of which are on the list.
Algeria, alongside Botswana, were added at the beginning of this year.
Since their addition, the Department of Justice has said that International Protection applications from both countries have fallen by 71%.
