We don't outsource our employees. All development, IT, etc is in-house.
That's in contrast to "offshore development", where the US team is augmented by contracted development companies in some other part of the world.
We have sponsored H1B visas, on occasion. Employees are required to have the legal right to work in the US, and are expected to make their legal residence in the US.
No, no it doesn’t. Given the significant advantages of hiring physically-local people, you cannot simply draw whatever conclusion you seem to desperately want to.
Overall that seems somewhat better than usual for small tech companies. I'd say taking 'dsr's assertion that his colleagues come from diverse backgrounds at face value may be a reasonable charity to give him.
