I applied on Jan. and was approved on March.
I applied early (my original due date was on August)

I also want to add. I will be sending back my EAD because my last name was misspelled.
I told them about this when I went to get my biomectrics done. They corrected it there but for some reason they didn't correct it at USCIS.

If anyone has the same problem and needs information please contact me.
