Congrats guys! A side question, how does immigration to the US work for these guys? EB-5 Visa? I hear tons of stories on how hard it is to immigrate to the States, but when Facebook does it for you all of a sudden it is no longer an issue.
Totally random but I bet an L-1 works here. They become a subsidiary of Facebook in the Netherlands, they've worked there for at least a year, they just transfer to the parent corp.
