Jobs belong to the employer, not to the worker. And the employer has the individual right (not always protected) to hire whomever he pleases. This includes the right to hire immigrants, legal or otherwise. I have no greater right to a job on account of my legal residence than does an illegal resident. Furthermore, every immigrant, legal or not, has a mouth as well as two hands. The idea that immigrants take jobs 'belonging' to Americans is boloney, both morally and factually.
