Can a US citizen applying for a Aufenthaltserlaubnis on the basis of Hochqualifizierte also apply for a stay permit for a fiance (also a US citizen). If yes, should this be done on the same initial application under the 'Family members joining you' or can this be done separately once the fiance arrives in the country? What type of stay permit would he need to apply for? Or is it easier for him to obtain a student visa since the fiance wants to study German anyways? What about obtaining a visa under the Lifepartner status? What factors are required to be considered a 'Lifepartnership'? Thank you for your help
