I’m a lawyer and I agree 100% with @Skates76. Pharmacy would be a great foundation before starting law school and for a wide variety of legal jobs. It would also be a strong foundation for many other graduate degree programs besides law. Note that if you are interested in patent law, you could become a patent officer/agent and work in a patent law firm even without going to law school.
I would also add that since you’re just starting your major, you have plenty of time to look at other majors at the university you are currently attending. It would be a lot easier to just change majors at the same place than to change universities. Yet you don’t have any idea what other major you would want to pursue – and you ask, “What major should I apply as?” There is absolutely no need for a different major if you are aiming for law school, and also no need for a different university. Just do well where you are, as your grades will be important when applying to any graduate degree program.
Is the real issue that you are doubting your choice of university? Since you can name the universities you are interested in attending (Ivy/top 30/Asian approved), but you can’t come up with any other majors – and you also don’t seem to have looked into changing majors where you are – I think you’re just having some second thoughts about your university. Brush those aside for now.
Many freshmen feel insecure about lots of things when they first start college. Just trust that everything will be fine, and make the most of your current situation. Since you don’t have clear direction for where to head other than where you are currently heading, you’d probably feel as much doubt and insecurity if you did manage to change majors and/or universities. Another student on another thread went through all the trouble to switch universities, and as a sophomore he has just started at a new place, and already he is whining about how much he dislikes it and wants to return to his former university. Doubts and insecurity will follow a person everywhere.
No major will doom you to a career you don’t like. In the real world, degrees apply very flexibly to many jobs, and many people change careers more than once. Engineering majors become investment bankers, fashion majors become salespeople, Spanish majors become real estate brokers, biology majors make documentary films, and anyone and everyone becomes a lawyer if they want to. And some very special and well-funded college drop-outs become billionaires. Don’t worry about all that right now.
Sounds like you got into a good program and you have the skills to be there and succeed, so that is where you should direct your energy right now. I bet if you go to career services and ask, or just do research online, you will find out many of the interesting careers that pharmacy majors from your university have had, aside from being a pharmacist at the local pharmacy. The links below will give you some ideas that make the most use of the degree, but they are just a start:

Keep in mind that there are countless lawyers out there wondering what to do with a law degree besides practice law – and there are articles, books and consultants all helping them find other careers. I currently write for a living with my law degree, and make use of my legal background by writing about legal topics.
