Ask HN: Who is hiring and willing to relocate developers?

All most all the companies in Ask HN are from North America and very few of them are willing to relocate developers. This makes Ask HN useless for a major chunk of Hacker News who don't have a work permit in North America. This thread is exclusively for companies who are willing to sponsor new Visa and relocate developers from other countries.
