This post is part of a series about what to do while your Priority Date is retrogressed, once you have received your I-140 Approval Notice from USCIS. It applies to cases which will be processed through US Consulates, and not to Applications to Adjust Status filed in the US.
To further clarify our earlier post about getting your Priority Date Corrected, we have been asked if it is possible to send the NVC a copy of your I-140 Approval Notice which has the correct Priority Date on it, so you can get the NVC to fix the fact they have listed your Priority Date incorrectly in their system. Unfortunately, the answer is that you cannot. You can send it to them, but they will not change the date based on your document. The document with the correct Priority Date has to be sent directly to them from USCIS.
