NRIs and OCIs can open an NPS account with the aid of a Point of Presence (PoP), a service provider through which they can open and operate the account. It is one of the best investment options for an NRI or OCI looking forward to planning their retirement in India. Both the NRE and the NRO account can be utilised for the OCI and NRI National Pension Scheme. All the subscribers will get a Permanent Retirement Account Number.
There are two stages in the NPS investment: Tier I and Tier II. Tier I is compulsory, and Tier II is voluntary. Tax benefits do not apply to an investment made in Tier II.
Furthermore, the investors can choose between Active and Auto Choice methods. With the Active Choice investment method, the investors can choose the allocation between equity, corporate bonds, etc. And with the Auto Choice method, the allocation is done automatically based on the age of the OCI or the NRI investor.
Some of the key aspects, regarding withdrawal, that need to be noted for this OCI and NRI investment in India are:
NPS Tier-I account withdrawals are subject to specific rules for financial planning and emergencies.

Partial Withdrawals: Allowed after 3 years for reasons like illness or education, capped at 25% of personal contributions and limited to three withdrawals.

Premature Withdrawal: Post 5 years, or within 3 for those joining after 60, up to 20% can be withdrawn as a lump sum, with at least 80% used for an annuity.

Normal Withdrawal: Upon reaching 60, or after 3 years, if joined post-60, up to 60%, is withdrawable as a lump sum, with a minimum of 40% allocated for an annuity.
For premature withdrawals, if the corpus is below ₹2.5 lakhs, or below ₹5 lakhs for normal withdrawals, the entire amount can be taken as a lump sum. Subscribers have the option to:

Continue contributions until age 75, offering flexibility in retirement planning.

Upon exiting NPS, options include deferring the lump sum withdrawal or annuity purchase until age 75, allowing for tailored financial arrangements.
