I am trying to decide on my area specialization for graduate school. I really like VLSI design. However, I get the feeling that because VLSI jobs are not common in the defense industry, the field is very saturated with people who don't have other options for EE work in the US (non-US citizens). For that reason, I am considering another area of specialization that is more useful across the entire EE industry spectrum. Control systems or signal processing, for example. I am definitely going to pair some VLSI courses with these topics, but I would not be going fully towards VLSI. Therefore, I would be able to apply for a larger range of jobs. Does anyone in the industry have any opinions? I could be really off target (I hope so), so please let me know.
