It's not like you can have a law for every FACT SITUATION (never heard the phrase).
Your examples are like a Japanese tourist caught stealing bread whose defense is "I only had YEN, and since there is NO MECHANISM by which a Japanese tourist can purchase bread with YEN, I had to steal some."
The fact of the matter is there are immigration laws. Immigrants who break them know it and know the risks.
The "risks" for an improper entry are a maximum $250 CIVIL FINE and deportation.
The visa system does have classes to fit people based upon who they are and why they want to come here. I used the term FACT SITUATION because that is what it amounts to. If you have a better term to describe why each visa fits a certain people / category, by all means correct me and I will use it.
The reality is that no visa exists that addresses the reasons and the people who enter the United States without papers, but for a legitimate purpose. It has always been questionable whether any law applies since we demand that people do something "properly," but fail to provide that "proper" mechanism.
You are acting like a dullard, much like the people that won't confine themselves to answering my simple questions. That is, most likely, because the answers are self evident. The immigration laws are unconstitutional because they are not uniform. The United States Supreme Court once opined:
"The general misconception is that any statute passed by legislators bearing the appearance of law constitutes the law of the land. The Constitution of the United States is the supreme law of the land, and any statue, to be valid, must be in agreement. It is impossible for both the Constitution and a law violating it to be valid; one must prevail. This is succinctly stated as follows:
The general rule is that an unconstitutional statute, though having the form and name of law, is in reality no law, but is wholly void, and ineffective for any purpose; since unconstitutionality dates from the time of its enactment, and not merely from the date of the decision so branding it.
An unconstitutional law, in legal contemplation, is as inoperative as if it had never been passed. Such a statute leaves the question that it purports to settle just as it would be had the statute not been enacted.
Since an unconstitutional law is void, the general principals follow that it imposes no duties, confers no rights, creates no office, bestows no power or authority on anyone, affords no protection, and justifies no acts performed under it . . .
A void act cannot be legally consistent with a valid one.
An unconstitutional law cannot operate to supersede any existing valid law.
Indeed, insofar as a statute runs counter to the fundamental law of the land, it is superseded thereby.
No one is bound to obey an unconstitutional law and no courts are bound to enforce it.

BTW, for you to claim to be a "teacher," your analogy sucks the big suck. A person goes to the bank and exchanges yen for dollars. There is a solution. If a foreigner wants to be a Guest Worker because an American offered them a job, there is no mechanism. Do you think that the people on this forum are stupid OR did you not know that?
The only "legal" way in (since you are too juvenile to understand the accurate legal term PROPER) for some people is to lie to the immigration authorities when all they want to do is exercise their Liberties. So, what you are advocating is to FORCE people to LIE to the immigration authorities in order to become citizens of a nation they do not want to be a citizen of? Are you effing kidding me?
