Time for another update on Blue Card implementation in the EU. I strongly advise everyone to double-check all the information here and on other sites. Your best bet is always to check official government sites and/or the local consulates for these countries to be sure that you have the most up-to-date and correct information.
A reminder - three countries are not participating: UK, Denmark and Ireland.
Also there are six countries that ostensibly are participating in the Blue Card program (they did sign up for it) but are now trouble with the EU for not complying. These countries are: Germany, Italy, Malta, Poland, Portugal and Sweden
That said, here is what I was able to find out about implementation in the rest of Europe.
The Netherlands: This site has some great information about the procedure. You can also find contact information for the relevant government agency, the Office for Labour and Highly Skilled Migrants, here. They list an address, phone numbers, e-mail and even a hot-line number if you have questions. It also appears that you can download the forms on-line.
Austria: Here is the procedure for applying in Austria. Looks pretty straightforward.
Hungary: Some information here and here about the Hungarian implementation.
Slovakia: This site is reporting that the law has been on the books since the end of July but implementation is delayed because they are updating the list of positions for which non-EU foreigners can apply. If anyone has better information, please leave a link in the comments section.
Belgium: This site has the procedure for applying in Belgium. This Belgian government site has more information (papers required and so on).
Spain: Here is the official government site for the Ministry of Labour and Immigration and here is a link to their fact sheets on procedures and requirements for entry.
Hope this helps. Good luck, everyone, and I'll post a separate update on France as soon as I have more news.
