I have seen similar questions asked but not from American Citizens.
My partner is a Swedish Citizen and we are engaged, I would like to know if I can visit Sweden while waiting for a residence permit, we have not applied yet but are planning to? From the US I do not require any visa to visit Sweden, I have visited twice before and only needed my passport.
I have looked at multiple official embassy and migration sites during my research but there are questions that remain a gray area.
I would like to be able to visit but don't want to harm my chances of getting approved. Also can I visit other EU countries while I wait, or none at all?
