What is the "Applicable country" field on the Icelandair check-in form?

enter image description here

As I entered my US Visa information in my booking with Icelandair, there is a field asking for "Applicable Country". I'm Indonesian but received my US visa from Germany, so do I enter Indonesia or Germany in this field?

It's not really clear to me what they mean, but since they already ask for the Place of issue, I think they mean the country the visa is for (the United States, in this case), though the fact that the whole section seams to be about US Visas in the first place is quite confusing.

@IhsanHaikal It's very puzzling. I would suggest phoning Icelandair to ask what they want in this field. If you do this, please post an answer to your question to help other people in the future.

@MJeffryes finally I got the answer from Icelandair after direct chat. They said I should put USA as the section is about USA visa
