Alp Mehmet from Migration Watch has told Daybreak that immigration is "an issue that we've got to look at."
The Labour party has vowed to reposition itself on immigration laws, with Shadow Home Secretary Yvette Cooper promising stronger checks on visas and "faster, stronger" immigration enforcement.
Mr Mehmet said immigration has an impact on schooling, housing and transport.
He added "I'm glad that the Labour party is now saying we've got to lower it."
