I am a Philippines passport holder who is currently living in the United Arab Emirates (UAE).
A few weeks ago, I applied for a Schengen visa and was approved (from Hungary). I previously intended to travel this coming September (out of panic). The reason for choosing September is because according to the documents required (for legal UAE residents), the residence permit should be valid for at least 3 months from the day of departure from the Schengen area. Since my residence visa would expire on December, I decided and rushed to apply for a visa instead.
However, just recently, I found a "loophole" in the Schengen visa application (for another country -- specifically Germany; although there could be others too) which didn't emphasize this 3-month residence visa rule.
My question is, can I apply for another Schengen visa (say, for October or November since this is my preference and not September) before my "supposed" September trip? Or say, while my visa is still valid (not expired, but haven't been used yet)? - My visa is from August 30 to September 20. - If I apply this week, I could get the visa in around 2 weeks, say August 29.
Or, should I wait for my visa to expire (September 20) and just apply for another visa instead?
I have had 2 previous Schengen visas that I've used last year and in 2010. It's only now that I am considering to not use and instead apply for a new one (if it is okay/possible to do so).
