Technically yes. My RD is 9/27/2002 and my I-140 got approved on01/03/03. So far there is no news on my EAD & AP. They say one gets EAD and AP approvals a couple of weeks after I-140 approval. But I saw on this forum where EADs got approved before I-140 approval.
Since I am not in a hurry to get EAD, I prefer to wait for it.
Good Luck to you.
