Pjiang,I am going to renew my EAD by pending I-485

Pjiang,I am going to renew my EAD by pending I-485, my I-485 have been pending more than one year. My L2 visa will expire in half a year if I do not renew it, normally how long I will be given for EAD renewal, will it be limited by the expired date of current status?

Thanks!
