The link is not opening for me now.
Edit : It appears that 2 way passport submission service is suspended until further notice due to curfew in New Delhi.
Please note that the Visa offices/High Commission/ Consulates will remain closed on account of the Covid situation & Curfew in New Delhi. The 2 way courier passport service stands suspended . Your passport pick up request will be serviced once business resumes. For latest information on resumption of services please visit

If your application is in Transit with the courier partner, at the Visa Application centre or submitted to the High commission/Consulate, please expect a delay in the processing of the application and return delivery of your processed passport on account of the restrictions imposed by the various governments owing to the Covid-19 pandemic.
