PPF: Maintain the account even if you shift cities
Individuals can open a Public Provident Fund, or PPF, account at any branch of State Bank of India, its associated banks, certain nationalized banks, and the post office.
If shifting residence, intra city or to another city, the account can be transferred to a bank or “account office” that the account holder chooses.
If an individual attains the non-resident Indian, or NRI, status after the account has been opened and is functional, he can continue with the account till maturity (though the money cannot be repatriated).
