AP approved for the main applicant, pending for dependent


Registered Users (C)
I applied for AP at Chicago Lockbox in Dec, ND in Jan. My applic was approved but my wife's is still pending. I have to travel to Europe in 2 weeks. It is possible to apply again for her at the local office? Will this make any difference? I've read here that some ppl got the AP from local office in 2 days, but I don't remember if this was before Dec 1st, when they introduced the Chicago Lockbox? Is anyone having any experience with such situation, please advice. My I485 apllic was transferred to Philly in Dec.
