Police Clearance Certificate of AOS - Immediate Relative

[AAMR]

Hello. We have applied for a PCC for my father (immediate relative based USA Adjustment of Status) with the Indian Consulate in NYC on March 16, 2021. We followed up with them last week about the status - where they informed us that the Police Clearance is pending from the police station in India as mentioned on the application.
Does any one know how long this takes and if we should follow up with the local police station in India? If you suggest so - then should it be at the Police Station or the Regional Passport office?
We are nearing the submission date on the RFE so wanted to check what we can do to expedite the process. Any help or suggestions will be appreciated. Thank you.
PS: The PCC is requested as a RFE after clearing the final interview as my father is 80 years old and has very weak finger prints - so were rejected twice.
