It's a bit of a long story, part of it is our fault and the other part fault on USCIS's part.
We actually sent our application and money order at the end of May but it took a little over 3 weeks before they cashed the money order, and then received the letter that the case was processing maybe 2 weeks after that I think. As for my husband, he forgot to sign his I-485 form. A very silly mistake that we are kicking ourselves over!!! We had triple checked everything else so many times, but we made two copies of the I-485 and guess we sent to one that wasn't signed somehow. Hence his application was mailed back while they started processing mine. So we sent back his application but this time USCIS (I'm guessing) didn't realize it was attached to my application as he was a beneficiary. Also in there rejection notice, they mistakenly said that the Fiscal Year had ended even though it was early August. So we sent his application back a third time, this time with a cover letter clearly stating the fiscal year end was 30th Sepptember and they started processing his case (it took about 2 or 3 weeks to cash his money order for the I-485 payment. That was probably the slowest part of the process. Then once his case went to the field office, they lost the receipt for our original DV payment (2x $330) which they actually did for my case aswell. I had to drive to the field office to give them the receipt and even after they had it on file they again said they lost it for his case. Doesnt make any sense to me. But s$%^ happens I guess, twice in fact. Then they scheduled him for biometrics for the 21st and as we all know now, visas were exhuasted on the 12th. So no, only I was interview end of August.
