I am an Indian national with Indian passport.
I am a Blue card (long term visa) holder in Germany. My passport is valid till August and I have to go to India for one week in mid-April. Therefore, I do not have enough time to apply for a new passport and a new blue card.
I heard that I cannot enter Germany again with the passport of less than 6 months validity (not sure about this info).
Please tell me if is it possible to get some document (from Indian Embassy in Germany or German Visa Office) which says that I am permitted to enter again...or something else which permits me to enter Germany with a passport having validity 3.5 months
UPDATE: My blue card is valid till August because my passport is also valid till August. The visa officer told me that a new blue card will be issued with the renewed passport. It is because the blue card has your passport number and therefore, new passport->new number->so new blue card.
