Ok, so we've had the discussion here on Lawnsite regarding illegal immigrant workers several times. Some of you have some major problems with businesses hiring illegals. Others don't seem to care too much. That's not what this thread is about. I don't care what your opinion on the issue is. Whether you support or oppose the use of illegal labor doesn't matter right now. I don't want to go there with this thread. But suppose an employer did want to make a diligent effort to make sure he wasn't hiring illegals - how would he do that? My argument has always been that it's next to impossible for me to tell which of my workers are illegals and which aren't. They all have social security cards that look real. They all have driver's licenses with their pictures on them. And I always have my friend, who is a cop, run the license numbers for me to check that they are valid. And most of them also have a Resident Alien card or something similar. So how am I to tell if these documents are legitimate or not? How is an employer suppose to know who's really illegal and who's not?
