From the New to Denmark Website,
If you have a visa that is valid for several entries for at least 180 days you can hand in an application for a new visa before the current visa expires.
- My current one is two-entry visa. Is it several-entry visa?
- I have used one entry, one entry unused. Then I can hand in the application for the new visa (back-to-back visa of the current one, no gap between them) before the current one expires? If I choose to do so, will my current one be cancelled by embassy?
- I plan to enter EU on Nov, exit it on early Dec. (current one expires on 12/31/2014), re-enter EU on 1/1/2015 using the new visa. Should I write the visa officer my plan when applying for the new visa? (so that VO won't cancel my current one.)
