Hi all, I'm from IT background and completed my engg. I gave Gre AND SCORED 310/340. I applied in 11 universities for MS in MIS. Florida international university (which generally asks for GMAT for MIS) gave me GMAT waive. But the course duration is 1 year, unlike other MS MIS programs in other universities. So my question is, is this one year course good ? Will I get to work there for 2.5-3 years like other MS people get (OPD) ? What would be the duration of Visa i would be getting ? Thanks in Advance.
