How long does it take to get your passport back from UKVI, NY when you cancel an on-going UK visitor visa application from USA?


I have applied for a UK visitor visa from USA and completed my bio metrics appointment at an application support center (ASC). I have sent my passport and supporting documents to UKVI processing hub in new york. I have not received any update on my visa application yet, but due to my personal concerns I am planning to cancel my application process. If I do so,

  1. After contacting UKVI to cancel my application, how many days does it take to cancel an ongoing visa application process ?
  2. In how many days can I expect my passport to be sent back to me from the UKVI processing hub, NY?

I am in need of this information. Can anyone please answer the above questions. I would appreciate it a lot. Thanks in advance!!!
