I will use 'security professionals' rather than 'ethical hackers'.
The whole world is witnessing a cybercrime as we are going towards the end of the timeline. All companies do require security professionals. But now the question is about the future.
Companies in India do not take this aspect seriously. While I was writing a research paper, I realised 'Only 5% of companies keep their data encrypted.' The Rest 95% either do not care or have no idea why security is important. But when It comes to the other part of the world, there is a huge demand for cybersecurity professionals. They hire people as they know security is some serious stuff. Plus they pay you well. Checkout the average salary of India as well as the US. It will be your choice of where to make your future.
Security professionals will be in huge demand in future, be it in India or the US.

Qualification is not necessary for learning ethical hacking, but web programming and networking background are quite enough for learning ethical hacking. But if you want to become a professional in this field, then you should have the strong practical knowledge on how program and network with Microsoft Windows and Linux system and if you are interested in becoming a professional in this field then CEH training is required.
The best defence is a good offence!
