I am going to Sweden to spend the Christmas and New Year with my Swedish boyfriend, for 16 days. I am employed and have traveled to other countries before (although always with my family; this is the first time I'm traveling alone). To make sure, I've also prepared my bank certificate, bank statements, passbooks, certificate of employment/salary/and leave. I'm also scheduled to attend CFO seminar to get my certificate. In addition, I also have his personal documents such as photocopies of passport, national ID, and certificate of civic registration.
My significant other is also in the process of authenticating an affidavit of support and guarantee, and invitation letter in the Honorary Consulate in Sweden. I also have his bank certificate and statements with me, plus his university registration (he is finishing his degree and not yet employed -- I'm sure this will raise red flags though :/ ). In case, you're wondering how he can afford to sponsor me, he inherited his money (and several stocks) upon his father's death. I have the inheritance document and proof of stocks. He also fully owns a house (also inherited from his father).
When I fill out the departure form, should I tick the "Tourism/pleasure"' box or "visiting family/friends"?
Should I divulge that I'm visiting my boyfriend, if asked the purpose of my trip, or should I just say I'm traveling for pleasure?
I'm 21. Legal age. However, I read in an article that a girl was not allowed to board her flight because she failed to present an affidavit of consent from her parents.
Do you think I should get one even though I'm technically an adult now and allowed to travel as I wish?
Have I overlooked other documents I might need to bring with me?
How can I be more assertive?
I've been practicing this lately because I tend to stutter (it's a problem) sometimes and I'm just generally awkward.
Update: I got through Immigration without trouble. I was only asked three questions about my employment situation and that was it. Thank you for everyone who answered this question and helped me out.
