voldemarv,
I agree, it is unusual. Chances of RFE on my EAD renewal application are very slim. It can not be on photographs (like most people get) because I sent clear color copies as per the new rule. Also, I sent color copy of passport etc....I took every possible step to avoid RFE's.
I was thinking the reason could be different, maybe they are about to approve my I-140 and I-485 together sometime soon, so why approve EAD ?.
I am not in a hurry to use EAD, so I did not plan on getting interim EAD. Guys, please post your thoughts, if you had a similar experience.
Thanks.
