There are many options for you to pursue. My one concern would be that having already had your overseas MBA downgraded here in the the United States to that of an associates degree, perhaps you should be pursuing something with more prestige and widespread respect. The two schools in the answer above would well suffice. Of note, UNC - Kenan Flagler is ranked as the #1 online MBA by US News and World Report. It is also a top flight school with big name recognition for its two year traditional, residential MBA program. It does not get much better than that. You would receive a standout education as well as be able to mine the alumni and networks of this prestigious school for job placement. I'm guessing that getting a great job is a primary goal. So as you consider the cost of attending, it would be wise to consider your return on investment as well.
That said, here are two lists for you to consider. The first is a list of some of the top online MBAs for marketing (it is by no means complete). The second is a list of the least expensive online MBAs (likewise, there may be many more out there to consider). As an international student, it may be more difficult for you to access the financial aid a US citizen can, and so I wanted to provide you a list of schools that offer a very cost-effective degree. Again, with any MBA degree, it may be wise to spend some time learning about the perceived value of a degree from an online school among employers.
Top Online MBAs in Marketing (Not in order of rankings) _
University of Virginia - Darden (equally as prestigious as UNC - Kenan-Flagler)
Least Expensive Online MBAs
Columbia Southern University (may be the best bang for buck at $6360.00 per year)
Colorado Technical University (also strong in marketing)
University of Maryland (also offers a highly respected full-time MBA program)
Neither of these lists represent all the schools you might consider. But they should give you a strong frame of reference for what's out there, what's well known, and most importantly, what may work best for you.
