22 years ago I was the girl visiting my american boy friend.Me and him was in our 40+. We spent qual time in Sweden and USA..
Most of the time it went "sailing through". Some times I got stopped.
He never got stopped in Sweden.
We eventually married.
Lived in Sweden. Just told them that I was married to an american and that we lived over seas. and was visiting.
Those time's no problems at all.
So it has a lot to do an the immigraiton agent at the time. Some just dont like foriegners at all.
Good luck. Times are harder now.
