Start from the approval date
I got my third EAD by mail yesterday. My second one will expire on 11/15/2003. Applied on 4/20/03. The approval notice said it is valid from 5/23/2003 to 5/23/2004. just got half year extended.
Guess what, it used to need 5-6 months to get EAD approved, several month ago, that is why we decide to apply in April. But they speed up EAD approval, just need one month now. They are joking with us!!!!!
No body knows this. maybe you apply now and get your approval after your second one already expire.
