Quoting from the NRI FAQs by NSE:
PIOs and OCIs do have parity with NRIs in respect of all facilities available to the NRIs in the economic, financial and educational fields except in matters relating to the acquisition of agricultural/ plantation properties.
You cannot trade intraday in equity (cash market). Short selling is not permitted and you have to take delivery of shares purchased and give delivery when you sell.
In F&O, intraday trading is allowed. Futures & Options is allowed in Rupee funds held in India on non-repatriation basis (NRO).
Yes, you can open a Trading & demat account. Check this link for the process
PIS Permission for NRO accounts are not issued any more, however, PIS accounts are re-designated as NRO Invest Savings account/Special Savings accounts. This is done since there involves a complex TDS calculation and a significant operational overhead being the reason not currently supported by most brokers.
The Notification No.FEMA.361/2016-RB issued by RBI brought about this change in FEMA where the PIS requirement for NRO was removed.
However, as a broker this service can be offered only when one can ensure that they can support the below process:
The meaning of the above is explained as under:
“(Net of applicable taxes)” - Like how the bank currently deducts TDS, brokers have to deduct TDS and make payout when the client is withdrawing funds. If the broker doesn’t know the acquisition price, 16.995% TDS of entire sell value has to be deducted and paid. Otherwise, it is 16.995% of capital gain. (Short-Term Capital Gain)
Once Zerodha starts offering the Non-PIS route, this shall be updated on the website and the process for the same shall be added too.
I’m sorry. But you must be mistaken. India doesn’t support dual citizenship. If you get citizenship of a different country (e.g. : U.S.) then your Indian citizenship is cancelled. Your friend must not have US citizenship. He probably has greencard or visa of US.
