One item not mentioned in the story that some people might find important: The Blue Card does not exist.
The Blue Card program is simply a proposal that would need approval from all EU member countries to go into effect, something not likely to happen.
Read the article carefully with that in mind and see how ridiculous it is to compare the time it takes to get to a Green Card to the time it takes to get a nonexistent Blue card.
The fact that the lobbyists have had to resort to threatening Congress with "vaporware" to get more guest worker cheap labor demonstrates how desperate they have become.
