Ask HN: Do startups hire overseas candidates?

How often do startups (YC or otherwise) hire from outside the US?

I know the H1B process is tough and expensive. What if the candidate was willing to pay the attorney cost and try to get the visa with little help from the company? It will be a good show of faith as well.

Or is it that most foreign talent isn't as good as those in the Valley/US?

Also, what about remote work; are most startups averse to this arrangement or there are so many remote candidates that getting selected is unlikely?
