Good question. On the one hand there is Galatians 3:27-29 "for all of you who were baptized into Christ have clothed yourselves with Christ. There is neither Jew nor Greek, slave nor free, male nor female, for you are all one in Christ Jesus. If you belong to Christ, then you are Abraham's seed, and heirs according to the promise."
On the other hand there is Mark 12:17 "And Jesus said unto them, Render unto Caesar the things that are Caesar's, and unto God the things that are God's."
Paul, Peter, John and each of the disciples disobeyed the law, as did Jesus, and were subjected to the death penalty for it. Would the brethren have been justified in turning them over to the law? Was Judas justified in turning Jesus over to the law because what Jesus did was against the law? Is that even relevant in the case of illegal immigrants? I have heard that argument made. What do you think?
