I have a multiple-entry Schengen visa (Tourist/Turismo) from the Italian consulate until the 8th of July, 2018 (valid from 16 June 2018) since I went to a conference in Italy from the USA (I am studying in the US on F1 visa). I need to go to Germany from the 20th to the 25th of August for another conference.
Here are my questions.
- Do I have to go to the German consulate (for me Atlanta) since it will be my only destination country in Europe?
- Do I apply for a new Schengen visa or ask for an extension of the visa (if such a process exists) depending on my date of appointment being before or after the 8th of July?
- If I need an extension, do I have to go to the Italian consulate I went to or to the German consulate?
