US Immigration from Bangladesh

Hello,

My wife is applying for her mother, who is currently here in USA in a B2 visa. So, she is applying i-130 and i-485 together. Here are some questions she has, if anyone can help that would be great.

1. During concurrent filling does she need to submit i-864 and i-693?

2. if i-864 is required then which address I have to send it out? NVC or USCIS?

3. is there any additional fees required for i-864.

4. Can I sponsor here where she is living in the same house hold with us and how?

My fiance and I filed for our K1 in December of 2021. We were approved, it went to NVC and was sent to the wrong Embassy. We have jumped through hoops trying to get it to the Embassy where he's at. They accepted the transfer. It's been a few weeks. Has anyone transferred theirs? If so, do any of you know if our case number stays the same, just change the first 3 letters to the letters of the country he's in? Thank you.

Hello,

Not sure if this is a dumb question, but would we need documentation of sending money back home to bring parents to the USA? I know it was needed when I applied for my husband, not sure if it would be needed for parents.

Thanks!

Should I apply for my parents to immigrate to the USA as a green card holder or wait to become a citizen?

My wife filled out I-130 applications for my mother-in-law and father-in-law back in March and June of 2022. Both of their cases got approved yesterday. For my mother-in-law's case, USCIS is forwarding the petition to NVC in NH, but for my father-in-law's case they've asked him to fill out Form I-824 (please see attached image). Both of them are overseas and both applications were filled out the same exact way. So we're trying to figure out why my mother-in-law's case was sent to NVC, but for father-in-law's case USCIS asking to fill out Form I-824 for which we would have to pay another filing fee. Anyone had any similar experience?
