I've got a national visa to Germany under Beschv 4 Managers and Specialists instead of the visa for Blue Card which I've applied for. Am struggling now with two questions:

1. can I get standard Blue Card based on this visa ?
2. If not, what will be the difference in terms of a period required to stay in Germany to get a permanent residence ? Would it be a status which could allow me to work in other German and EU companies ? Could I bring my wife in Germany without a need for her to pass A1 exam in German ? Thank you in advance.
