I'm trying to figure out when we can starting filling the DS-160 and any other documentation. Do you have to wait until the case reaches the foreign embassy and you get a welcome letter from the foreign embassy saying they are ready? I thought you could fill it when you get a case number from NVC, but here's my issue...
I kept reaching out to NVC via their public inquiry and they finally told me that they got my petition from USCIS and they gave me my case number and invoice ID. However, when I go to CEAC login, after entering those two pieces of information I simply get a generic page about the k-1 visa: "K visas are nonimmigrant visas that assist spouses or future spouses of American citizens in entering the United States. As with all nonimmigrant visa applicants, a DS-160 must be filled out in order for a consular section to process the case." and there's an OK button at the bottom of that page. Not helpful. Doesn't log me into anything specific to me. And If I try to check my status in CEAC via their status check page, I run into a different issue: If I choose NON-IMMIGRANT visa type, I get "Invalid Application ID or Case Number." If I choose IMMIGRANT visa type, I get "Your search did not return any data." Is that because they haven't sent it to the foreign embassy yet? Or it hasn't finished being registered in their system? I'm not sure.
I see that I could go start filling in the DS-160 application online, but if I'm understanding my research correctly, I think that's a bad idea until I officially get told to do that.
I'm just not understanding the timing. I know that I have to be patient, but I also don't want to be sitting around waiting when I could've been working on documentation. So what are my next steps, if any?
Additional info:
In their email response to my public inquiry, NVC said "Due to your petition type, you will not receive a request for fee payment or document submission." That really confuses me. I'm 100% sure my fiance has to fill out a DS-160, so does that just mean that I myself won't be asked to submit any documents? I don't know why their communication is so unclear to me.
Also, they said "All case parties will be notified when this petition is forwarded to the assigned U.S. Embassy/Consulate General." So that leads me to believe I should just keep waiting I guess.
