re: I just learned one of my favorite contractors is not a US citizen.

I think that if people were being honest there would be a lot more with stories similar to yours. I'm sure we've all had our favorite housekeeper, nanny or babysitter, elder caregiver, etc. whose work ethic and devotion to the family are exemplary.

Sadly, this man and his family have had their opportunity to do the right thing. Ignorance of the law is not an excuse for breaking the law. There are tons of resources in Spanish and many other languages that explain the laws of this country and the steps one must take to conform to those laws.

There are tons of places, including churches, that provide free English language lessons. There is no good reason not to speak English adequately after nearly a quarter of a century in this country.

Fact of the matter is that, by continuing to employ him, you risk running in with the law yourself. Can you really afford to do that? He should consult with a good, legit immigration lawyer sooner rather than later. In the meantime, you will regretfully have to use someone else's services and invite him to come back when his status is legal.

btw, I'm a naturalized citizen myself and my family followed the law every step of the way. Because we respect this country and its laws.
