The Portfolio Investment Scheme (PIS) allows registered Foreign Institutional Investors (FIIs) and Non-Resident Indians (NRIs) to buy and sell shares and convertible debentures of Indian companies. FIIs must be registered with SEBI and obtain permission from the RBI through a designated bank. They can purchase securities through registered brokers on recognized stock exchanges. The payment must be made through inward remittance or funds held in an authorized dealer's account. The ceiling for overall investment for FIIs is 24 percent of the paid up capital of the Indian company and 10 percent for NRIs/PIOs. NRIs can invest under the PIS through designated branches, with limits on the paid-up value of shares and debentures.

The acquisition of property in India by individuals residing outside the country is governed by certain regulations. Indian citizens residing abroad can acquire any immovable property in India, except for agricultural, plantation, or farmhouse properties. For individuals of Indian origin, the definition is more specific, excluding citizens of certain countries. Transfer of property is also regulated, allowing residents outside India to transfer immovable property to Indian citizens or persons of Indian origin, while agricultural land and farmhouses can only be transferred to Indian citizens residing in India. Property acquisition can be done through purchase, gift, or inheritance, in compliance with the foreign exchange laws. Additionally, non-residents with approved business activities in India can acquire property necessary for their operations.
