hey, its all about whome you are getting married to. I am not sure if you are boy or a girl.
If you are a girl , its could be a lil complicated because in my opinion its a bit risky to include a boy in your application as adependent/spouse because of the back ground checks issues unless the boy is some one you know very well. Still I doubt boys about the clearance of thier back ground checks etc because they are more out going and are supposed to be involved in any activities at any point of time which may hinder your application too.
If you are a boy, it should not be a big problem , because girls are likely to have no problems in thier back ground chceks and usually its considered as safe to include them in your application as dependent / spouse.
PS: Well, this is purely what I think and is strictly a personal observation.
