RBI clearly allows Investment abroad and holding a international bank account for individual upto 50000.00 USD per annum ( including forex trading and stocks ) however , if you plan to send large fund via bank transfer , you will have provide a fill in declaration form to the Bank ( for is available at RBI website) . This rule came up some time in 2005 . I think is now raised to 100K usd per annum please chk this info.
