John Lannon told RTÉ radio’s Morning Ireland that such a move was “a knee-jerk reaction” to the problem of a shortage of accommodation.
Restricting the numbers coming to Ireland seeking international protection was a retrograde step, he added.
Visa-free travel for refugees into Ireland from 20 “safe” European countries will be suspended for a year (from today) in a hardening of the State’s immigration policy. It means that people who have been granted refugee status in other countries can still apply to travel to Ireland, but will need a visa to do so.
The visa-free travel arrangements for Ukrainian nationals fleeing the Russian invasion will be unaffected.
Mr Lannon said there could be cases where people were not able to get visas. Ireland should be creating safe pathways and there was a need to ensure that if someone needed to seek asylum they could do so, he said.
Putting barriers in place and placing people in tents should not be the solution, he added. If tents have to be used, it should be “very temporary”. People who have lived through the trauma of war should not have to sleep in a tent with strangers.
There needed to be a long term strategic approach with a national lead to coordinate planning instead of “scrambling” for accommodation, and Ireland should learn from other countries, according to Mr Lannon.
The news comes as the Government said Ukrainian refugees will only be expected to stay in tents at a military camp in Gormanstown, Co Meath for a week.
Some 150 people will be moved there on Tuesday.
On Monday evening, it was announced that the Government has agreed to temporarily suspend the operation of the Council of Europe Agreement on the Abolition of Visas for Refugees (Council of Europe) for 12 months.

Minister for Justice Helen McEntee said the Government has not taken the decision lightly.
“However, where there is evidence that there may be abuse of such systems, the Government must act swiftly to mitigate the risks to maintain the integrity of our immigration and international protection systems and uphold public confidence in those systems,” she said.
“In recent months, we have seen that the visa exemption provided for in the Council of Europe Agreement is being exploited, including by some who enter the state and subsequently claim international protection, despite having already been granted such protection by another European state.
“The suspension of the operation of the agreement is temporary and will be reviewed in a year’s time. In the meantime, Convention travel document holders who want to travel to Ireland can apply for a visa under standard visa arrangements.”
