What can I do about my girlfriend's parents not approving of relationship?

Answer Not much can be done to make someone's parents like you and to approve a relationship between you and their daughter. You might not want to rush them as you could be this girls first romance and maybe they aren't so worried about you as they are concerned about her. Maybe they think she's too young to get involved with a guy on a relationship basis and that's their right, she is their daughter.
