As a chemical engineer, you can work in a diversity of different fields- petrochemicals, commodity chemicals, food industry, semiconductor industry etc. to name a few. You can work in a chemical plant as a process engineer, but you can also choose to work as a sales engineer, product engineer, in R&D etc. So there are a number of different kinds of opportunities available. And I am not sure about your comment about no chemical engineering option in India. You are clearly mistaken about that, as I studied chemical engineering in India, and there are several wonderful Universities and Institutes that offer degrees in chemical engineering.
