I-290B questions after I-495 denial

[Katie Lorenzo 9]

My husband's I-485 was denied on May 28th and we decided to move forward with both an I-290B (motion to reopen) as well as refiling a new I-485.  We were just missing pg. 10 (the last page for additional information) of our I-864.  We received an RFE to resubmit our I-864 and when uploading our RFE documents online, instead of submitting the PDF with our complete (all 10 pages) I-864, I accidentally submitted a jpg that only showed the first page.  Our denial notice stated we failed to submit a complete and signed I-864 "with all pages present" as the reason for our denial.  I'm preparing our I-290B for my husband (he is the applicant and is addressed in our denial notice as the person who must appeal) but I have a couple questions.

 

Question 1: Part 2. Item 4: Requested Nonimmigrant or Immigrant Classification

 

How do I answer this question?  My husband came on a K-1 visa and we married and sent off his I-485 within 90 days.  I can't find any information about what his requested classification is.  He didn't come on a spousal visa, but do we state CR1 as his requested immigration classification or do we put the generic LPR?  I also found these possible immigration classifications: 

CF1Spouses, entered as fiance(e), adjustments, conditional

IF1Spouses, entered as fiance(e), adjustments

 

Question 2: Part 7 Additional Information

 

Do I leave this blank or just make reference to the brief I plan to attach as a separate letter to USCIS making our case, along with our complete I-864 originally intended to submit for our RFE.  I'd also love to see a letter anyone else might have submitted.  I haven't had much luck finding one on the different forums.

 

I'm aware most people decide to refile and don't submit a concurrent I-290B.  We decided it's worth the $800 for the chance that our case may be reopened.

 

Thanks in advance to anyone with insight!
