If you really interest in MKT, maybe you can find a job in that area first, then pursue higher degree after 2-3 years later. DA is a part of MKT function, but if you don't like it, you don't need to force yourself to accept it, the final decision is just depend on yourself, follow your heart!
I am a current student in U.S right now. Based on the economy, it's really hard for international students to find a job. If you can get experience by a few years working, you can do a much better School than those three. However, a few years later, you may just got promotion or find a better job in the good economy, then your plan for education in U.S may be postponed.
