US Immigration from Taiwan

Hi Everyone!

My fiance and I are currently working on the I-129F form and are unsure for 2 parts if you could kindly guide us.

- Beneficiary's employment history: Since everything is in his native language, do we need to have it translated into English by a professional?

- Beneficiary's parent's name Part 2 item 24a-c. His parent passed away couple years ago and we do not know his English name on the passport. In this case, how should we complete this section correctly?

Thank you all in advance!

Can I upload the passport of a U.S. citizen on the applicant s birth certificate?

In I-864, what time points do 5th and 6th refer to?

I m currently preparing for the joint guarantor. When I fill in the I-864 documents,
the following six documents are ready to be uploaded to NVC CASE. Are they correct and not missing?

1. sponsor I-864 PDF
2. sponsor w2 PDF
3. sponsor' tax return PDF
4. sponsor pay stubs PDF
5. sponsor passport PDF
6. sponsor ID PDF

In addition, apart from 2019_TaxReturn and 2 Federal incone taxy,
should the joint guarantor provide his 2019 TAX Transcript documents?

If these six documents are correct, do you upload six PDFs separately?
Or, except for I-864, a single PDF, and all the other five documents are uploaded in one PDF?

In the PART 5 column of I_864, the applicant only needs support for one beneficiary. Is the total number of 3 in HOUSEHOLD SIZE correct?
