It's easy to open an NPS (National Pension System) account online as an OCI or NRI. To begin, go to the NPS website and fill out the registration form. A current passport, documentation of your NRI or OCI status, and an Indian bank account are required. Depending on your requirements, select either Tier 1 or Tier 2 accounts. Once your documents have been submitted, finish the e-signing procedure. To activate the account, make sure you fulfil the eligibility requirements and contribute the first amount.
