US Immigration from Philippines

Background

I'm American, wife is Filipino. We're married for 2 years, had baby in Philippines. We're now "conditionally IR-1" and got an interview date. We have her uncle as a financial sponsor.

Need help:

What updated documents do we need for the interview from me and her uncle?

So far I can think of W2s, tax transcripts, 1040 tax form, 6 months of pay stubs.

Are we missing anything?

I'm scheduled to have an interview on October 29th in the Philippines. Unfortunately, my fiance and I did encounter some financial issues that sets us back quite a bit. I don't even have m medical scheduled yet. I wanted to try re-scheduling instead but there's are no available dates that are open yet. Would it be safe to cancel it to have it re-scheduled instead? Or would it be better to just keep waiting for dates to open so I can reschedule?

My apologies if this is in the wrong category.

My wife has entered the United States under an IR1 visa. There is no stamp in her passport and now her employer is asking for the stamp. How do we go about getting this stamp?

I finally had NVC accept my payment. I have my I-864 ready, but probably will not have my taxes squared away until next week. Can I file my I-864 now and send my taxes later, or do they need to be sent at the same time? Thank you, Dave & Joyce

Hello,

Review there is from my ex-wife's experience in 2011. Is there a way to clear it out?
