Interesting... based on this thread it seems like it's possible to request a change with the NVC with a K-1 too. Is there something I'm missing here? When and how does the embassy get decided? Is it based on where the beneficiary is residing at the time of filing the I-129F? I haven't been able to find that info. Thanks to everyone for the replies

She is a dual citizen with Italy, she is in Switzerland based on their free movement agreement with the EU. Ok, good to know... it sounds like changing embassies would be more of a pain than I thought originally. It is looking more certain that she will be moving sometime soon, so maybe it will be best to wait until after the move

We're unsure of the country - she is originally from Argentina and currently living in Switzerland, though she may be moving back to Argentina before this is all over. According to this, both countries' embassies take ~40 days, though there isn't a lot of data points there.

Based on what I've read online, it seems like the consensus has been that the CR-1 is strictly better than the K-1 because the processing times were similar but the CR-1 allows you to work as soon as you enter the US. However, according to VJ, the processing times for the I-129F have halved in the past year while the I-130 has stayed roughly the same. I understand that the benefits of the CR-1 are significant, but right now our goal is to get together ASAP, so the K-1 seems better for us. Has the online consensus not caught up with the data or am I missing something? Even if VJ has a smaller, self-reported dataset, the trend seems quite clear
