I would strongly urge you to not pursue membership into any organization at this time. If you are committed to an organization you will wait and pursue membership when it is made available to you. Use this time to save up for some business attire (stick to neutral colors), learn more about the organizations (via members in your area, NOT those on the internet) you are interested in, get and maintain a 4.0 GPA, become an active member of at least 2 other campus organizations, get some community service experience. I could go on but you are in college so use those brain cells.
Good luck.
