Trending @Infosys; Notice Period on Bench

I am going to be released from current project in Infosys and after that I am planning to resign since I am looking job outside India. So how the notice period is going to be for an on bench resource who has resigned? I want to serve 3 months notice period because I need 3 months salary for some expenses. Or will they agree to pay 3 months salary and release me? I am working as Senior Consultant here with last rating Met Expectations. Also is this rating good or bad?
