It's because the Immigrant Visa Unit at the embassy processes and interviews K1s. So you pick immigrant for checking status, making appointment, paying, etc. Something to watch for (could be different depending on Embassy)--your status will say Immigrant and date may change a few times, but when it switches to saying Non-immigrant, it's a sign they are close to printing your visa. Then status will say Issued once it's printed and a done deal. Watch for it. 

Omg it worked! Thank you so much!! I can have a good sleep tonight haha

As a K1, when checking your case online at CEAC you have to select "immigrant visa" as it is treated as such even though it is a "non-immigrant visa". Don't ask why, as no one has been able to articulate why!

@Naes Thanks a lot! Now we kinda have an idea of what to say in our call 😌I think we will wait to call till the website date gives me a date after our NOA1 though, as we are still in the normal processing time like you said...Crossing my fingers there will be a lot of movements this week!
Also I wanna take this moment to give a shoutout to @Naes, thanks for being an awesome person! You keep us sane during this USCIS wait madness 👏
