The time one must carry a SR-22 may vary in Virginia but typically it must be held for 3 years.

The Virginia Department of Motor Vehicles notes that normally when three years have elapsed, from the effective date of the suspension for which an SR-22 is required as part of the reinstatement process, the DMV relieves the vehicle owner of the requirement of furnishing proof of financial responsibility. To see if this is true for your situation contact the VA DMV.
