Question: The employers claim to hire the H-1Bs because they have work experience in specific software skills. How is it that the H-1Bs possess skills the Americans don’t?
Often the H-1Bs don’t have the background they claim. An audit by a U.S. consulate in India found that fraud was quite common. Similarly, reports from American programmers who work with H-1Bs indicate that rather than having work experience in the given skill, many H-1Bs either have only had a quick course or are learning the skill on the job. Ironically, the latter is what I recommend that the employers have older American programmers do, but the difference is that the H-1Bs are much cheaper than the older Americans, so the employers do this with the H-1Bs but not with the older Americans.
