Can an NRI extend the tenure of NPS beyond 60 years?

Ideally, the eligibility criteria to invest in NPS is for individuals between 18-60 years. One cannot start to subscribe to NPS after 60 years. However, if one is already a subscriber of NPS and wishes to contribute beyond 60 years, it is allowed to be done for a further period of 10 years i.e. one can continue contributing till the age of 70 years but post that one needs to exit as per the NPS exit rules that are applicable at the age of 60 years.
