My girlfriend has already applied for a visitor visa for Germany to meet her brother starting from 4th March 2020 and valid for a period of 90 days. We intend to get married In India middle of February and she wants to apply for a spouse visa before she leaves India. Is it possible to apply for the spouse visa while holding a visitor visa or should she cancel the visitor visa before applying. I have also heard it takes a lot of time to get a spouse visa and we would like to travel to Germany together. We are both Indian citizens and I am blue card holder in Germany.
