The Garda Representative Association has criticised suggestions reserve Gardaí will be deployed to areas with a high number of migrants.
It's one of the measures being considered to provide additional resources to the 10 regions taking in the most migrants in the country.
Extra nurses in GPs and more English Language teachers are also being examined.
President of the GRA, Donegal's Brendan O'Connor, doesn't think deploying reserve Gardaí is realistic.
