US Immigration from Brazil

I keep seeing people on VJ say that if you get an expedite approved at USCIS, it doesn't affect anything but USCIS and you'll have to request a new expedite at NVC and then at the embassy.

Is this true?

If so, how does this work for K-1 visas? I've seen several posts that K-1 visa's CAN'T be expedited at NVC because they're "automatically" expedited, but my understanding is that NVC doesn't process your case until the embassy is ready to receive it... and my embassy (Rio de Janeiro) isn't receiving any cases that aren't "emergencies" (which I assume means manually expedited rather than just "it's a K-1"). So... how do I get my case to the embassy if I can't expedite it? This is all so confusing lol. I appreciate any guidance.

Hellooo...

Anyone from Brazil did biometrics ( here USA) and waiting for approval waiver?

Hello, I would like to ask if the "Statement(s) from your employer on business stationary" is needed for a job you recently got laid off. Like, let's say the interview is December and my fiance gets laid off in November but soon finds another job. Does he need the Statement from the previous job or just the current one even though is pretty recent?

Hello!

I have seen many old posts about this but nothing recent (post COVID days) so am worried laws have changed...

My husband will enter the US and I understand the permanent resident card takes a couple of months to arrive... Can he travel outside of the US while he has not received the card?

Thanks so much!

Hello everyone! I have filled the I-751 form last week and they received the paperwork on Friday. I sent the form allowing them to use my credit card info for the payment of the fees. I also sent a check with a note saying that just in case they can t process my card for some reason they can deposit the check. Long story short.. they haven t done either and I was wondering How long it takes for them to generate the payment and to send the NOA1. Thanks!!
