The regulations pertaining to immigration law that must be memorized do not exist for the sake of bureaucracy. These rules codify justice as that concept is applied to foreign nationals. When an agency does not follow its own regulations, foreign nationals have the RIGHT to sue in federal court through various proceedings. The names of these proceedings include writs, petitions for review and habeas corpus.
Knowing that foreigners have inalienable rights places the study of regulations in a whole new light. Each time the Citizenship and Immigration Service issues a decision which departs from precedent or that is based on impermissible factors, there exists at least one foreign national (or a whole family of foreign nationals) who can achieve his or her goals only if an immigration specialist recognizes the rule that has been broken, the injustice that must be remedied.
