Need Clarification-Another requested doc after 221g

[Abby & Andre 27]

My fiance had his interview a month ago and he was given a 221g for my divorce decree and asked to send it in. We sent it in right away and have been waiting to hear back. Well, now he received a letter in the mail and I received an email saying this:

Hello,

Thank you for the inquiry.

After careful review of your file we have deemed that the following documents will be needed for the completion of your visa application.

1. Proof of U.S. liquid assets from petitioner

I created a thread in the K-1 forum already and the consensus is that they're asking for a letter on bank letterhead with the date acct was opened, deposits for last 12 mos, and current balance. I am in the process of getting this from my bank.

My question is: Why are we receiving this now? Are they saying my income is not enough and want me to prove the gap with assets? Or they just need to see a steady income over the last year? My income by itself is a little over $2000 over the 125% for a household of 3 (I have a daughter). As far as liquid assets go, I have a couple thousand in my savings and that's it. I am scared we are going to be denied because of income, but I make enough so I am puzzled as to what exactly the issue is. Please advice.

No idea what's going on but it's best to get them what they want. Do you have a joint sponsor just in case?

I don't have a joint sponsor. I didn't think I needed one since I make enough with my income. Wouldn't they have said something at the interview if my income wasn't sufficient? Or said so in this new letter we have received? Does everyone have to turn in this letter from the bank and we just overlooked it? I am definitely in panic mode.
