I am not a lawyer nor an Indian Citizen. But here is some information that might help. If you plan to marry an Indian you have to provide notice to the Marriage Officer of the district in India. After a waiting period, you get married. Then you can apply for a PIO card (Persons of indian Origin) card based on your wife and that allows you to live and work in India. After 7 years of bliss and living in India, you can apply for citizenship. This according to what I could find for you on line.
Regarding FATA. It applies more to airlines than the rotor world right now.
I would not worry about the 2010 rule. It's all about supply and demand.
Good luck.
