Actually, there is. What is lacking is the will.
1) Stop providing services to illegals, with the exception of emergency medical care (followed by deportation), there should be no services for illegals.
2) Do not allow licensing or diploma for illegals. No drivers or professional licenses, no college degrees or high school diplomas.
3) When caught, make them pay for their own deportation if they have the assets. In any case, upon deportation all their assets here should be frozen and then used to fund deportations, just as drug and other criminal activity seizures.
4) Provide employers with access to a DB to check status and then charge them double what it cost to deport each of their illegal employees. Post the names of the businesses that get caught harboring illegals in the local papers, sing them out on the local news (like the police blotter).
5) Enlist the aide of state's police. Give them guidelines and training and then certify them, just as we do with many other competencies within law enforcement.
6) Enforce existing law.
Do that and so many will self-deport. Take away what's in it for them here and they'll return on their own, or try some other place. Might also help if we make an announcement that we're going to do the above and any who self-deport are eligible to apply for future [legal] visa and immigration programs. The ones we catch, starting say six mionths after the announcement, will no longer be allowed to ever legally enter the US again.
