Austria Vice Chancellor Reinhold Mitterlehner said on Monday that Austria can not accept more than nearly 100,000 refugees.
"Around 90-100,000 -- a lot more will simply not be possible," said Mitterlehner.
Since September, thousands of refugees have fled from conflict and poverty in the Middle East and Africa have entered Austria.
Austria still expects to receive approximately 95,000 asylum applications this year, a great difference when compared with 28,000 asylum seekers registered in 2014. Only 38 percent were allowed.
"That's not the sum which comes in addition every year," Mitterlehner told reporters on Monday. "Those who leave, who get integrated...those who return to their countries - that's roughly the room for maneouvre which we have for the next few years."
Chancellor Werner Faymann, a Social Democrat who has mostly made decent statements about refugees said that Austria should increase deportations of some asylum seekers who did not meet the criteria needed for asylum.
Thousands of refugees have been marching towards western European countries, following a route through Greece-Macedonia-Serbia-Hungary-Austria, forcing the EU to face its worst refugee crisis in decades.
