How do I report an employer that continuely brings illegals into the US illegally. The 1800 number simply puts you on hold. Is there a website or email address I can use to report this?

It would help if you mentionned what 1-800 number you are calling, below is the correct number for reporting things like this. If this number places you on hold you'll just have to hold.

From the ICE website (Immigration and Customs Exforcement)

"To report any suspicious activity please call 1-866-347-2423. Emailed reports of suspicious activity or "tips" are not accepted at this time. "

But again, don't really expcet any large raid on them, there is little real inforcement of illegals into the US at this time.
