Though it may not be the official language, English certainly appears to be the standard and can be very helpful in making your way. Being able to speak the "standard language" is more insurance for an immigrant to know they're not being pissed on. It's a helpful tool to get by in our society. I think to allow illegals to continue to come through and not have the tools necessary to get by here, would be a disservice to them. They can't vote. They may not speak english. They essentially can be taken advantage of by any shady employer. Being here legally is much better for them as well as us. Can we boot them all? No...but we need to stop the flow of illegals and work on some way of openning the doors for the people that are here and get a policy that will encourage them to get here legally. Once people are documented and legal they can demand higher wages, they don't have to hide and they have some recourse if they're getting screwed by an employer. We also would know who is here and what they are doing.
