I-797 Receipt number?

[Duke 0]

I recently received the I-797 (Notice of Action) which lists a 13-digit Receipt Number begininng with "WAC" followed by 10 numerical digits.

Is this our official case or application number? Will this number follow us all the way through the process?

Specifically, is this the same number that will be used to identify our application in Australia?

We were successfully able to get the medical exam done in advance, as my fiance will be spending the three months in the States while our application is pending. However, the doctor needs the "case number" to put on the medical form(s) to complete & release the medical forms.

The WAC number goes with you the whole time. It's what you use to create your account at USCIS to check your status, etc. I'm not sure if it changes when you go from Dept of Homeland Security (USCIS) to Dept of State (those are the visa folks).

No. That is your application number. Your case number will assigned by NVC after approval of your K-1.

That's correct. The WAC is your receipt # which is completely different from your case #. Once your I-129F is approved by CSC, it'll go to NVC. Once they receive it, they will assign your petition a case # which usually starts with 3 letters specifying the consulate city. In my case it would be BOG# for the embassy in Bogota, Colombia.

Since you're going through CSC, you still have about 2-3 months to go before you can get your case # from NVC.
