One of my Iranian friends has also obtained German citizenship. Now, she has two passports: an Iranian and a German. However, she wants to just use her Iranian passport to apply for student visa from the Netherlands in order to start a PhD program there.
She is currently in Iran and does not want to use her german passport at all.
(1) Can the embassy understand that she has also a German passport? Can she be given the student visa of the Netherlands on her Iranian passport?
(2) Will she be able to enter the Netherlands with the visa on her Iranian passport, or will she have some problems upon entering the Netherlands?
