Illegal immigration to New York City
Illegal immigrants residing in New York City come from many parts of the world, especially Latin America, Asia, Eastern Europe, and the Caribbean. About 70% of them have paid work, in catering, construction, retail, driving, cleaning, and many other trades; at least in catering, their wages tend to be lower than those of comparable workers.
