What are my chances

[CalmLogic]

One more question, is it easy to take distance learning course in Staford, UIUC or Columbia without the need to provide undergrad degree, GRE,... etc ?

You really just a need a credit card They don't check anything for non-degree seeking students.

Regarding your GPA, yes, it is technically possible to be admitted with a 3.5, but the odds still seem very much against you as your academic/research background needs to be able to compete against all other students in the world for a small number of slots. For example, an American student who went to UIUC for undergrad CS was rejected from Berkeley and some other top schools for the MS:

I applied to 10 schools, heard responses from first week of February up until 14 April, and since all schools got back to me by the 15th, I was able to respond and go where I wanted.

Accepting me: University of Illinois - Urbana / Champaign, Brown University, University of Michigan - Ann Arbor, Columbia University, University of Colorado - Boulder.
Rejecting me: Stanford University, University of California - Berkeley, University of Washington - Seattle, University of Texas - Austin, University of Maryland - College Park.

No school offered me assistantships or fellowships, so my decision was based on my opinion of the school more or less. My undergrad was at UIUC, and I knew the program well, it was a good program. I visited at Brown and I'd seen Colorado in the past a few times. I chose to stay at UIUC, and being such a high ranked school, I know it can't have been the wrong decision.

My stats: 780/87% quantitative, 440/42% verbal, 810/80% CS subject, 3.33/4 cumulative, 3.5/4 technical, 3.75/4 CS only.

Granted, this person did not have any publications, but he was just applying for an MS degree and had some priority as an American student coming from one of the top CS departments in the world. Still, he wasn't seen as good enough for Berkeley since Berkeley gets over 2,000 applicants for the fall semester and must reject around 95 percent of its applicants, including applicants from Berkeley, CMU, and MIT.
