Hey guys, my i-130 priority date is on the 25 July 2007 , (F3- Category).

So far i have my Receipt Number and My Case number.

When logging in the CEAC, its asking for my INVOICE ID NUMBER which i do not have or NVC did not send me it.

I attached a image below can you please explain to me what does that mean and why i did not received and INVOICE ID NUMBER AS YET.

It's also 12 year since the petitioner filed an I-130 forms for married sons/daughter , Our priority date is on the 19 July, 2007 and was approved by the USCIS on the 10 February 2010. I would like to know when we should be expecting letter/documents from the NVC/USCIS.

And Based on an estimate how much more its going to take for our priority to be Current.
