Non-resident Indians are not allowed to open a new PPF account. However, if a resident who has a PPF account becomes an NRI later, the account can be continued till it matures on a non-repatriation basis.
Existing PPF Account of NRIs
If a resident who has a PPF account becomes an NRI after the account is opened, they can continue to contribute to their PPF account until its maturity on a non-repatriation basis. However, the account will not be eligible for extension beyond the maturity period of 15 years.
