This question already has an answer here:
I am an Indian national, and I have secured a Schengen visa for my travel to Germany which starts on 17th September 2018 and ends on 5th November 2018.
The visa is a type-C multiple-entry visa, which is valid from 17th September 2018 to 20th November 2018, for a period of 50 days.
I want to visit a tech conference which takes place in Lisbon, Portugal, between 5 and 7 November 2018 and also watch a Champions League match on 8 November 2018.
My problem is I exhaust my 50 days if I stay in Germany from 17th September 2018 to 5th November 2018. I will have to leave the Schengen area on 5th November.
My question is:
Can I apply for a Portugal visa for 5th November to 8th November, even if I already have a Schengen visa valid till 20th November (which expires on 5th November as I deplete my 50 days)?
Also, it is possible to apply for this visa when I am already in Germany?
