Ask HN: How can my company sponsor visas?

I run CPAP.com. When hiring we often find that the most qualified candidate's application is dependent on being sponsored by our company. We want to open our hiring process up to this pool of people but want to both stay inside regulations and keep the process lean.

Has anyone put together a tutorial or primer on this for hiring developers and marketers?

I googled around as I wrote this and have included some resources and my comments on them.

A lot of gov-speak. Hard to see how this translates into my specific situation.

A nice overview, but I want to hire developers and marketers. What kind of visa is that? Interviewing non-visa candidates works for us, we do it anyway, but how many interviews is enough interviews? Also, it says apply early. I'm guessing on Jan 1st the giant google/microsoft/amazon hiring machines send them all in. How much of a chance do I really have?

A hat tip to these folks for the depth. If we go down this road, I will be checking our process against their FAQs but I don't find this helpful for building the process itself.

This is nice but the "click here to download a timeline" link is both blue and not a link.

Any stories, tutorial/blog links or professional recommendations are appreciated.
