Immigration is not easy, legal or illegal. This is particularly true when the would-be host nation has a government that cannot function, run by people who cannot solve even simple problems, much less decide monumental issues like who stays and who goes.
Consider the developments in just the last week or two. Suppose you are a farm worker from somewhere in the Americas, and you wish to come to the United States to work, temporarily, and legally, in full compliance with U.S. laws and customs. You are invited by an employer in the United States to work under a temporary visa program called H2A. You arrive at the border at the appointed time, expecting to be processed through the bureaucratic channels in the normal day or two, but are told to wait ... for weeks. The State Department computer that processes the visas has “problems.”
