In my opinion, chemical engineering is a good career option in India and outside India. But, it has a wider scope outside India. It's a broad field and can lead to opportunities in several fields (academia, chemical industries, R&D, even in ISRO and NASA!). So, pursue chemical engineering (only if you are interested in it). All the best!

Chemical engineers work in offices as well as laboratories. They find employment at industrial plants, refineries and locations where they monitor or direct chemical operations. They usually work with design professional and technicians or work on-site.
The industries that employ chemical engineers are as follows:
Architectural engineering
Basic chemical manufacturing
Scientific research and development services
Resin, synthetic rubber, and artificial synthetic fibers and filaments manufacturing
Petroleum and coal products manufacturing Biotechnology and pharmaceutical companies

The scope is decent.
Good luck.
