Great guide, I'd love a similar one for Green Cards.

For instance, does a Masters in CS qualify you for an EB-2 filing? A search shows that the employer would have to give evidence of the advanced degree being necessary for the job. Usually you wouldn't need a Masters degree for a programmer role but I'm wondering how strict this is in practice.

Concretely, if you were to enter the US on a H1-B for a SDE role with BigCorpA and had a Masters degree in CS, could you immediately file for a Green Card under EB-2 category?

Assuming that everybody else performing that role at the company has a Master's degree (or equivalent) there is nothing stopping filing the labor certification on day one.

As with anything immigration related. Consult a lawyer, not the internet.
