I got two internship offers from different organizations in UN in Vienna. One is 4 months and another one is 2.5 months. The thing is the note verbale will be strictly accorded to my internship agreements. I will apply the first visa-d first and then apply for the second visa. Is this possible to have two consecutive visas at the same time?? If possible, is it ok to stay more than 180 days with two consecutive visas? Thank you so much for your help.
