Narrative:
Busy session on final landing the expressway visual approach to runway 31. My final started to get backed up and I needed to vector northbound over manhattan for spacing. Aircraft X was eastbound over manhattan at 3;000 feet when I cleared him for the approach. The approach clearance instructed him to cross dials; which was about 3 miles east of his position; at or above 2;500 feet. In between this aircraft and dials; aircraft Y was level at 1;900 feet at the border between lga tower's airspace and my own. Aircraft X descended to 2;500 feet; directly overhead of aircraft Y at 1;900 feet.when lga is landing left traffic to runway 4 the tower may only work VFR aircraft at 2;000 feet up to the lga 240 radial. When lga is landing left traffic to runway 31 the tower may work VFR aircraft at 2;000 feet up the lga 230 radial. Even though it's only a 10 degree difference; in such tight airspace it makes a very big difference. If aircraft Y was west of the lga 240 radial there would not have been a problem. I recommend the tower's airspace be restricted to the lga 240 radial when landing left traffic to runway 3.

Title: N90 Controller makes a request to change airspace related to IFR operations and VFR Helicopter operations.
Narrative: Busy session on final landing the Expressway Visual Approach to Runway 31. My final started to get backed up and I needed to vector northbound over Manhattan for spacing. Aircraft X was eastbound over Manhattan at 3;000 feet when I cleared him for the approach. The approach clearance instructed him to cross DIALS; which was about 3 miles east of his position; at or above 2;500 feet. In between this aircraft and DIALS; Aircraft Y was level at 1;900 feet at the border between LGA Tower's airspace and my own. Aircraft X descended to 2;500 feet; directly overhead of Aircraft Y at 1;900 feet.When LGA is landing left traffic to Runway 4 the Tower may only work VFR aircraft at 2;000 feet up to the LGA 240 radial. When LGA is landing left traffic to Runway 31 the Tower may work VFR aircraft at 2;000 feet up the LGA 230 radial. Even though it's only a 10 degree difference; in such tight airspace it makes a very big difference. If Aircraft Y was west of the LGA 240 radial there would not have been a problem. I recommend the Tower's airspace be restricted to the LGA 240 radial when landing left traffic to Runway 3.
