China came up with a distant second with 340,000 resident non-immigrants. This included 40,000 temporary workers and 260,000 students, the report said.
"Seventy-five per cent of Indian nationals were admitted as temporary workers, making up about 40 per cent of the temporary worker total, whereas about 75 per cent of Chinese nationals were admitted as students, comprising 30 per cent of the student total.
