This is rather easy for the typical HN crowd. For example, to get a working visa for Germany (Blue card) you "only" need to find a job that pays more than 50000 Euro/year. In a nutshell, that is all.
Had no idea about this, thank you for passing it along. This part is particularly interesting:
> Holders of an EU Blue Card can enter another Member State without a visa after 18 months and apply for the EU Blue Card of that Member State within a period of one month.
And it looks like Americans (at least for now...) can go to Germany before they're even approved:
> Exceptions apply to nationals of Australia, Canada, Israel, Japan, the Republic of Korea, New Zealand and the United States of America. They can enter Germany on a visa-free basis and can apply to the competent immigration authority in Germany for their future place of residence for an EU Blue Card within three months of entering Germany.
