You got to be crazy. Since when do we allow illegal immigrants availability of our courts. Civil war to follow.
We allow everyone the availbility of our courts. Citizen, non-citizen, resident and non-resident alike. Likewise, most of the civilized world does the same. If you're defrauded for example, by a Brit, you can take your case against him to a court in the UK, even though you're not a citizen.
