The investment must generate employment for at least 20 resident Indians in every financial year. Each year the PRS holder must submit to the FRRO/FRO the Form FC-GPR, the Annual Return on Foreign Liabilities and Assets filed with the RBI with the RBI acknowledgement, and the income-tax return, to show the investment conditions are met, plus auditor-certified details of employment generated for resident Indians. PRS works as a multiple-entry visa with no stay stipulation. The official source does not state a minimum period for holding the investment.
