Hello aspirant,

If you submit your documents earlier for the verification, then it will done soon within five to six hours. Also, the time taken in while verifying the documents is usually depends on the no. of candidates who have applied and from center to center. Anyways, if you submit your documents in the last moment, then it will take a hell lot of time to get verified, maybe more than ten to twelve hours or even more than that.

Hope, it helps you.
