Did you know that you could have 15 years of working in the Bay Area experience and still be refused a German blue card because you majored in Physics or EE instead of CS? But mere work visas were easily obtainable a couple years ago with a signed contract.

There are two options to get Blue Card. One is education, but second is professional work for I think 10 years above certain threshold salary (very low threshold for IT, even by EU means). So that 15 YOE IT engineer can certainly apply and get Blue Card. The only nuance is that it needs to be full employment, self employment doesn't count or is problematic iirc.
