I have an approved I-140 under EB3. I want to port this to EB2 catetory. To do this I am thinking of doing my Master's degree(MBA) from University of Phonix. I heard that U.S. master’s degree should be in the same field. I am working as a software developer, so will MBA come under same catr****y of my work, or do I need to specialize in MBA-Project Management or MBA- Technology Management?
