In which form(s) do the permits come?
This is an easy one, albeit somewhat baffling, for you kind folks.
Do you get the permits in the form of a separate document or are they stickers on your passports?
I thought I might find a sample from someone posting theirs on one of the threads but to no avail. The reason I ask is because I have multiple passports, both EU and non-EU, and would like to know if I have the option of not sticking it in either.
