My understanding is: I get a D-type/National Visa from the German Embassy in my country, and once I get there in Germany, I will apply for Blue Card.
It was like this until someone told me that one can also apply for Blue Card Visa right from the German Embassy in one's own country, and now I'm confused.
Although I checked with the German Embassy of my country, and on their website, nothing is mentioned related to Blue Card Visa, and all they provide is: National/D-type work visa among other categories, and I couldn't learn anything related to getting Blue Card Visa.
Now, my question is: is there any benefit of getting the Blue Card visa over the National Work visa before entering Germany, as eventually, the National Wok Visa could also lead to a Blue Card in Germany if one qualifies for it.
