My friend has an Indian Passport with no surname.
In the passport, the name is as below:
Surname:
Given Name: John Doe
The German Consulate states to write the Given Name as Surname in case there is no Surname:
Surname/Last Name: John Doe
Given Name/ First Name: John Doe
And I contacted Emirates Support, and they said to write:
Surname: John Doe
Given Name: FNU
Has anyone been in the same scenario, because I want to write whatever the issued VISA has. Or has anyone travelled with FNU in their ticket to Germany without facing any troubles ?
