> 5) A determination by the Service that the equivalent of the degree required by the specialty occupation has been acquired through a combination of education, specialized training, and/or work experience in areas related to the specialty and that the alien has achieved recognition of expertise in the specialty occupation as a result of such training and experience. For purposes of determining equivalency to a baccalaureate degree in the specialty, three years of specialized training and/or work experience must be demonstrated for each year of college-level training the alien lacks. For equivalence to an advanced (or Masters) degree, the alien must have a baccalaureate degree followed by at least five years of experience in the specialty
This is ridiculous in both directions. In one direction, someone can have 12 months of tech industry experience with more knowledge than a Masters degree holder. In the other direction, it's also possible to have 30 years of real experience in the tech industry without being particularly skilled labor (the apocryphal "three months of experience, repeated a hundred times").
My lawyer told me you need a 4 year degree equivalent, and 4 years of experience can convert to a year.
If you have zero university education, that would be 16 years' experience required, based on that lawyer's legal instruction.
