I read through this whole thread and I'm not clear on the exact details. I had an I-130 for a parent approved almost a year ago (February 2023) but we have not started the NVC process. I logged into the CEAC with the credentials given in the welcome letter. Is logging in sufficient to keep the case open? In the pinned post it seems like more is needed, including submitting DS-260, but this is Step 6 in the NVC process, so I am confused. Any advice appreciated!
