I am an Indian expat living in Krakow and my work visa is valid until December 2018. I have already applied for my as well and my dependant's blue card in May. The process for the blue card is currently taking 5-8 months.
The problem is that we have to travel back to India in December to attend a marriage in family, and that is obviously important to be a part of. I will only be able to return in January 2019 when my work visa would have expired.
I would like to know if I have any option to get any visa extension or if I can get the blue card process expedited. Can I travel to India on the basis of the positive decision if I get it before leaving?
