US Immigration from Taiwan

A Neighbor just sent her I-485 package a couple weeks ago. Yesterday, they received an RFE for the I-864 income. Would you use adequate assets to resubmit...or would you get a qualified joint sponsor with spouse? Why?

My beneficiary is from Taiwan. The PDF fillable field for address has a character limit. I can put this in manually, but if others have experience with this and can utilize other fields to input this?

Beneficiary address (sample):

1F., No. 1-1, Aly. 1, Ln. 111, Sec. 1, Amazon E. Rd.

In the address field, I can only get it down to:

NO1.1 ALY1 LN111 SEC1 AM (character limit reach)

I am applying for my fiance as a beneficiary. My fiance was in the US a few years ago on a I-20 Student Visa but is not currently residing in the US now.

On form i-129f Edition 03/21/2022 it states that,

Quote

If your beneficiary is currently in the United States, complete Item Numbers 38.a. - 38.h.

Questions:

38. He or she last entered as a (for example, visitor, student, exchange alien, crewman, stowaway, temporary worker, without inspection):

38.e. Passport Number:

38.g. Country of Issuance for Passport or Travel Document:

38.h. Expiration Date for Passport or Travel Document (mm/dd/yyyy):

My fiance is not currently in the United States, do I leave blank Item Numbers 38.a.-38.h.? My fiance was in the US on a Student Visa before (I-20) and I do have passport information.

I'm a Naturalized U.S. Citizen. Do I feel out Alien Registration Number (A-Number) on my i-129f? I am the petitioner. I became a U.S. Citizen 30 years ago if that matters. Thanks first!

I am petitioning for my fiance and noticed my name is different on my Certificate of Naturalization. The name I used on my Certificate of Naturalization is now used as my middle name. For example, my Naturalization Certificate shows "John Smith Lee" where Lee is my Family Name. For my passports and my driver license, I use my given name "Michael" John Smith Lee. Should I fill out section 7.a. & 7.b. under Other Names Used with the same exact name on my Certificate of Naturalization?

TLDR:

My family name is : Lee
Name on my Certificate of Naturalization is John Smith Lee

Name on my Passport and Driver License is Michael John Smith Lee

Would I need to fill the section as Other Names Used? (7.a. & 7.b.) - I have not used this name in any other legal documents. All my documents are either Michael Lee or Michael John Smith Lee (Passport & Driver Licenese)

The full name that I wrote on my i-129f is:

Family Name: Lee

GIven Name: Michael

Middle Name: John Smith

Thank you first!
