1. Printed copy of the email
2. Valid Passport
3. Planned date of arrival in Germany
-- I just wrote an informal letter informing them my arrival date in Germany. They did not demand any e-ticket copy from me.
I was given 2 choices on how to submit the documents:
1. Personally show up at the German Embassy during office hours.
2. Call the call center of the Embassy and request for courier pick up.
-- You can actually send the required documents through your choice of courier, however, the Embassy do not guarantee the timely printing & releasing of your visa.
I choose to call the Embassy's call center. They gave me instructions
-- the official courier of the German Embassy is Air 21.
-- Fee for round ticket of document (to-&-fro German Embassy) costs 320php and is payable upon pick up of your required documents.
-- Fee for one way (from German Embassy) to your place is 160php and must be paid upon delivery.
Hope it helps!
Happy Leap Year!!!
