Coould you expand on this? Is it something like "they don't do H1 visas" or "there are occasional incidents of borderline racism" (I heard something to this effect in a conversation recently) or something else?
Hm, I just saw this question, sorry. I should definitely clarify. I witnessed NO racism or xenophobia at Apple. I was treated very well throughout my internship.
To the best of my knowledge (2006), Apple does H1 visas, but they don't sponsor green card applications. When your H1-B expires, they'll have you work elsewhere until you're eligible for an H1-B again. This is based on a small sample (rumors).
