Ah, perhaps you misunderstood then. I certainly didn't mean to imply that one would look to the poem for a n indication of what the immigration process is like!
I definitely agree with your point about making illegal immigration less desirable. One way to do that would be to make legal immigration more possible, as often, for many people without proper education, illegal immigration is the only viable option. This should not be the case. Why would legal immigration be harder than illegal immigration? One way to achieve this would definitely be to fine those who hire illegal immigrants more heavily!
