How Long Does It Take to Receive the Hard-Copy Response from FBI by Post to an Indian Address?

Hi there,

I reside in India.
The response to my request for Identity History Summary Check from the FBI has been generated a month back.
As far as my knowledge goes, I have opted for a hard-copy of the response to be mailed to my India address as well.

It’s been a month but I have not received any mail from FBI.
Any idea how long does it usually take to receive the mail to an Indian address?
Also, is there any means to track back my application to validate whether I have opted for a hard-copy response as well?(To the best of my knowledge I have opted for the same).

Thanks in Advance!
