Can I be admitted to a master's in the USA after a 3-year European bachelor's program? I am an Indian citizen and I'm planning to go for my bachelors to Germany. Since schooling in Germany is 13 years in length, I'll study 1 year in India before going there. I wanted to ask that after completing my Bachelor's in Germany, will I be eligible to apply for Masters in USA straightaway right after my BS (I plan to pursue a BS in Computer Science). I had this doubt in my mind as BS in Germany would be 3 years compared to that in USA which is 4 years.
The answer to your question is yes, no, and maybe. It all depends on where in the US you want to go.

As Brian indicated in his answer, these are some universities that don't accept a three-year bachelor:


San Jose State University
University of Idaho


However, there are certainly universities that do accept a three-year bachelor:


Stanford University
University of Minnesota
Columbia University
New York University (Wagner)
Almost all business schools accept a 3-year degree (including Harvard, MIT), source


And then there are who evaluate the three-year bachelor on a case-by-case basis:


University of Michigan (Rackham Graduate School)
UNC Charlotte


Certainly, this list is incomplete. So, do your own search if you like to apply in the US, and if a university does not state anything about the three-year bachelor, ask their Graduate Admissions office.
