good day gentlemen
The list of documentation is as follows:
1. Bank statements to proof you have enough funds to sustain yourself. We print that from the internet.
2. Travel insurance
3. Itinerary
4. Letter of invitation.
We had all these documentations except the invitations letter. We spoke to the Austrian consol regarding our problem. We have been travelling for more than a year. Luckily Austrian do travel extensively. Our passports are also proof of our travel integrity.
I believe after they made the necessary interpol searched, and didn't find us on the most wanted list in the world, the visa was issued.
We are an exceptional case.
