To be realistic, if you are Indian national with IT background, it will be VERY VERY VERY difficult to get into aerospace/defense product management (especially outside of India).
1) Software and hardware are very different industries. Software is about building the best product possible because the cost is in the initial investment, and there's almost no scaling cost. In hardware/physical products, cost management is a critical part of market success. As easy as that sounds, people with software background have hard time transitioning to physical product company. Case and point, Google has not had any success when it venture into hardware space.
2) Aerospace/defense industries concern national security. Any significant involvement in those industries require citizenship in the home country. That is a rule written in stone, and there's no way around it.
Thanks for sharing nice info
