It is the homebuilder (contractor) who hires legal subcontractors, who in turn, employ illegal aliens. Many illegals are now "legally" running crews with their young adult anchor babies' social security numbers. Multitudes of illegal aliens in the construction industry work as supposed "subcontractors ", utilize 1099 forms, and never pay any taxes. Very difficult for Americans to compete with this, which is why you see illegals framing nearly all the new houses.
