Germany expects up to 300,000 migrants to arrive in the country this year, the head of its Federal Office for Migration and Refugees said.
Frank-Juergen Weise told the Bild am Sonntag paper that his office would struggle if more people came.
But he said he was confident the number of new arrivals would remain within the estimate.
More than one million migrants from the Middle East, Afghanistan and Africa arrived in Germany last year.
