I am new the forum and I am trying to get some guidance. I want to know, what can a degree in Public Administration, Criminal Justice, Political Science or Foreign Policy and International Relations do for me?

Public Administration: work your way up in a bureaucracy or a non-profit organization, also applicable to many business positions. Make sure you get an internship.
Criminal Justice: police officer or law enforcement-related government job. If worse comes to worse, you can be a private i. You should probably get an internship for this one too.
Political Science: You'll end up like me, searching for just about any job. Eventually you'll find the kind of job that accepts any liberal arts degree as evidence of your ambition and flexibility. I majored in sociology, which is actually open to more jobs. Political scientists generally don't get social work or counseling-type jobs. You might be able to work for a political advocacy group, but you'll start out with very little or no pay. BUT if you keep your grades up, you can go to grad school. The PS degree will set you up for a masters degree in public administration, business, or law... or possibly a Ph.D in PS so you can be a professor.
International Relations: Learn Arabic, Persian, or Chinese as a supplement. They'll hire you for a lot of government agancies, including as an intelligence analyst or a diplomat. Also some private sector jobs will be able to use you for their foreign accounts and such.

Alot of the smartest arts students major in political science. Basically you get a government job or become a lawyer.

Public Administration is basically Political Science, just a different name. If you are committed to working at a desk job in some government building, its for you.

Criminal Justice people usually are police officers or probation and parole officers. The fancy word for it is Criminology.

International Relations is alot of political science. I am somewhat interested in this, learn one or more of the languages JavaBlack recommended, it definitely helps. There will be alot of jobs in this field, embassies are emptying out because of old retiring folks. Sometimes its offered in the business department as well.

Except I just recalled something. Don't learn Persian. It's not a language. Farsi is the language. Those are the top languages due to national security and expanding relations. India is the other country we do more and more with, but English seems to be the unifying language there... perhaps Hindi or Farsi would be useful though.
Another thing to consider in international relations: at New York University they have a master's degree specifically aimed at students who want to work with NGOs or the UN.
