Oh, it absolutely is everywhere. (FYI labour arbitrage has been going on for thousands of years, it's a thing). Not so much 'ethnicity' but 'visa leverage'. Sun Microsystems and others faced scrutiny during layoffs for protecting H1Bs over American workers. Given the leverage that companies have, they often pay less. Also - foreign workers will generally have a lower salary requirement if they come from poorer countries. This is also the case in Alberta Oil fields where investors try to get temp permit visas for foreign workers (China, Philipines) because hiring Canadians is brutally expensive. It becomes de-facto ethnic because the workers tend to come from specific regions.
