US Immigration from Brazil

My spouse has been here one year, and he is still waiting on Work Authorization

So my brother's son was born in the US but left at a really early age. Now my brother wants to come here with him now that he is over 21 and we both thought that he could petition for him while his son, the US citizen was abroad. On the I-130 it asked for an address in the US, which I believe should have been his current address but we entered mine (US based) since we thought it was something that was needed for communications to be sent. Now the case has been sent to the NVC (approved) but thankfully we caught it early.

Is he out of luck? Does he son needs to enter the US first and start all over?

Question. I sent the paperwork to remove conditions in July 2021 and received the extension letter 10 days later. According to timelines, I was supposed to receive either a letter for interview or a 10 year GC in the mail. Instead, I got another 2 year extension letter. Putting me in a 4 year conditional GC.
Anyone going through the same? My stuff was sent to the CA office. I wonder if at this point it s better to apply for citizenship already.

I paid the AOS fee on 4/17 and then that transaction took the money out of my checking account on 4/18. The NVC portal showed the AOS fee as 'Paid' on 4/20.

I then proceeded to make the payment for the IV fee on 4/20. That transaction took took the money out of my checking account on 4/21. The NVC portal showed the IV fee 'Paid' on 4/23.

Both show paid, so we upload all of our documents and wait for DQ as of 4/25.

As of today, 5/5, I receive an email from NVC about the IV Fee saying "Unfortunately, the receiving bank was unable to accept your payment for the following reason: No Reason Provided." My checking account still has both fees deducted though -- and now the NVC portal is saying 'Not Paid' for the IV Fee and there's a message saying the IV Fee was rejected.

I have read through lots of experiences people have had where it would take a long time to show 'Paid' after they made payment...but that common issue isn't this one. This issue is (I think?) nuanced because the money left my checking account, NVC showed paid, and now it shows unpaid. Has anyone ever heard of this? Should I be worried? What should I do?

Ol ! Vou viajar ao Brasil pela primeira vez em seis anos e vou alugar um carro.

Eu tenho a minha driver's license e fiz o tal Inter-American Driving Permit, um documento que aceito no Brasil e no Uruguai. Posso antecipar algum problema caso, por exemplo, eu for parado numa blitz? Algu m teve recentemente uma experi ncia nesse sentido?
