I think this saga may be easiest to explain in chronological format.
August 12--my then-fiance arrives in U.S. on a K1 visa
August 24--we get married (not sure if this is relevant to the SSN issue)
September 1--My husband has an appointment at the local SSA office to apply for an SSN. At the appointment, the case manager says his I-94 immigration document cannot be immediately verified, and the process of verifying it may take up to 4 weeks.
September 29--After waiting 4 weeks with no update, we call the SSA office. We are told by an agent that their system shows they were still waiting on "immigration." Around this time, I learn that if the SSN doesn't get issued by November 9, when the I-94 expires, my husband won't be issued one, even if he applied long before then. So the rest of the actions take place with that urgency in mind.
October 1-12--We continue calling SSA periodically, and are never given much info. We are given the phone extension of the person handling my husband's case, but she never answers when we call.
Around October 12--We see in the SAVE Case Check website that USCIS had returned the case to SSA. (Later, another case request shows up for October 13, which also gets returned to SSA.)
October 13-23--we try calling the person handling my husband's case many, many, MANY times, leaving MANY voicemails, with no response ever.
October 25--we talk to an agent at the local SSA office. After she initially says they're still waiting on immigration, I tell her the SAVE Case Check website shows they've returned the cases to SSA. She looks into things more and tells us that, in fact, USCIS was waiting for the case manager to send them additional documents. She sends an email to the case manager, asking her to take action.
October 28--after talking to another agent, we finally end up getting a call from the person "managing" my husband's case. She tells my husband that the SAVE system was showing "Status Mismatch" for his I-94 and there was nothing she could do. She said she could send him a denial letter, so we could take it to immigration to try to have them correct it. I pointed out that by the time that got sorted out, the I-94 likely would have expired. She says that maybe immigration could extend the I-94 since the delay wasn't our fault. (I assume that she just made that up, since I've never heard of anything like that.)
This afternoon, I've emailed the CBP's SFO I-94 corrections email account with the relevant info to ask them to correct my husband's I-94. As far as I can see on the I-94, though, nothing is incorrect. Further, the CBP phone number said the corrections take 5-10 working days, meaning there's next to no chance it will be processed in time. I don't really know who's at fault with the mismatch, but it's extremely irritating that the person handling my husband's case at SSA didn't let him know about the mismatch sooner, when there might have been time to still get the SSN.
So with this tale of woe, does anyone have any input? What could be causing a "Status Mismatch"? Is there anyway to remedy it beyond emailing the CBP's I-94 corrections account , when we don't even know that nature of the mismatch?
