The Taoiseach has said he is hopeful new sites announced for Ukrainians moving here won't be targeted by protestors.
Nearly 2,000 beds for Ukrainian refugees are being created in Dublin, Laois, Limerick, Kildare and Cork.
They will offer accommodation to those fleeing the war for 90 days.
People arriving from Ukraine will also get a reduced weekly allowance from tomorrow.
Speaking in Boston, Taoiseach Leo Varadkar said he's not expecting major protests outside the centres.
"Generally speaking when it's come to providing welcome centres or residential centres for Ukrainians we haven't seen a large amount of protest or difficulties with that," he said.
"Sadly the difficulties that have arisen in terms of protests have been more often connected to people seeking International Protection rather than those coming from Ukraine," he added.
It follows concerns of a 'humanitarian emergency' outside the International Protection Office (IPO) in Dublin city.
A number of asylum seekers were moved back onto the streets after receiving temporary accommodation during heavy snowfall earlier this month.
Over 1,000 asylum seekers are without accommodation in the State, with growing numbers camping outside the IPO on Mount Street in the capital.
