Re: Why don't you have my case at the NVC yet?
When you complete a petition (I-130, I-140, etc.) for an immigrant visa, you send it to United States Citizenship and Immigration Services (USCIS) in the Department of Homeland Security for approval. If USCIS approves the petition and you wish to process for a visa outside the United States, USCIS will send you a Notice of Approval (I-797) and send the petition to the NVC. It often takes longer for the petition to arrive at the NVC than for you to receive your Notice of Approval. Please wait up to six weeks after receiving your Notice of Approval before contacting NVC. Once we receive your petition from USCIS, we will give it a unique NVC case number and send you a letter notifying you that we have your petition and what to do next.
