Airspace Structure
While being vectored to the LOC 31 at LGA in the vicinity of the DIALS intersection; I spotted a drone operating near us. We were at 4000 ft MSL headed NE to overfly LGA. The drone appeared to be a white quadcopter operating at or slightly below our altitude approximately 2000 ft off our right side heading west. No evasive action was required by us; we continued on our assigned heading and altitude and reported the sighting to ATC. The FBI has since followed up with me.
Air carrier First Officer spotted a drone near their altitude of 4000 feet while on vectors to LGA Runway 31 near DIALS intersection. No evasive action was required.
