US Immigration from Vietnam

Just helping my wife submitted two I-130 for sister/half-sister. The first case was easy and solid since it was the same mother and father. However, the second case is little bit complicated: mother is the same, but father is different. A side note: all the parents(all 3) are passed away long time ago. For the second case, beside the birth cert that showing the same mother, what's else do we need to submit to prove the relationship?

On my wife's N-400 it says I ( USC spouse) was married two times. I was married three, two before and to her. On all other applications, I-130 and I-751 it lists all three and we have always sent in both divorce certficates. I did upload both with the N-400. Should I do something before her interview which is May 20 or just have her point out the error as soon as they start the interview? We have always sent both divorce certificates on all applications. I'm sure they will see the error.

My fiancee is Russian born and is currently living in Ho Chi Minh City, Vietnam. Her birth certificate, vaccine record, and police certificate are all in Russian. We're searching for someone who can translate/notarize these documents from Russian to English in Ho Chi Minh City.

On that same note, once a document is translated, does it then need to be notarized or is it the other way around? Do some offices offer both processes at the same time?
Any assistance is greatly appreciated.

Lastly, it appears I will need my (the petitioner) original birth certificate and copies there at the interview. Has this been the case for other petitioners who have applied at the US embassy in HCMC?

Hi,

Does anyone have an example of a relationship timeline that the Consulate Officers in HCMC are expecting for the K-1 Visa interview? I don't want to bore them with a 5+ page essay but at the same time I would want to be as detailed and concise as possible as to not receive a denial slip. Also, does anyone know if they are accepting additional photos and evidence (receipts, gifts, rings) during pre-check-in on the day of the interview? I am hoping to make another trip before the interview and will like to submit engagement and post-engagement photos.

Thank you!

We just received notice on the USICS site that my wife's N-400 interview has been scheduled. I assume this is a combo interview but there is nothing on the letter that states that it is. If it is a combo interview does the letter state that both she and I attend? Also, my wife's 17 year old daughter immigrated with her. Does she need to attend for eith the I-751 interview or the N-400 interview? We did file I-751 for each.
