How to work in India as an Actress?

Ok, I'm in a pickle.

I really want to move to Mumbai, and try out for Bollywood Films. I am not Indian, and therefore require a business visa to legally work there.

For this, I must provide a letter from an Indian employer claiming I'm to work for them, and for what period of time. My visa will then be issued.

The thing is, as an actress, work is not guaranteed in this way. I need to go there, and audition before work is promised to me.

So how do I get around this? I really need to hear from other non-indian actors experiences, and how they managed to move to india, or anyone who knows how to get around this.
