Does this sound like your topic?
This is a question in the DS-160 ,that is causing some doubts at a lot of places .
"have you any specialized skills or training, such as firearms, explosives, nuclear, biological, or chemical experience?"
Does this apply for weapons or does anyone obtaining a degree in that particular field (i.e. Chemistry ,Biology etc) also needs to mention YES and explain.
Also is there a different process of visa approval once you answer YES to this question . Any examples or precedents would also help .
