NEW EAD

Could anyone help me? I had two EAD's in the past (fist one & renewal) based on economic hardship applied through school (F-1). I want to apply for another one again based on the same circumstances as above. Can I look for a local INS office or should I mail my application to INS main office? The reson is that I think applying through local office wouldn't take too long to get the card.
Thank you for any answer!
