I'm curious if anyone who filed at the NSC but was transferred to CSC can answer this. What received date was on your NOA? The date received by NSC or the date received by CSC? Looking at the USCIS receipt timeline updates, I don't know whether to look at the processing dates for NSC or CSC. According to the certified mail return receipt, our file was received by NSC on November 5th. In other words, will we get penalized for being transferred to CSC by getting a later filing date than if we had filed at NSC? In our case it doesn't really matter since we filed with plenty of time, but I'm curious if this means people filing with NSC need to take the potential transfer lag into account when deciding when to file their petitions.

According to the Ombudsman, here's what USCIS is supposed to be doing. I'd be interested to find out if they're actually doing it this way or not.

i filed to nsc also and then trasfered to csc and the date that nsc recieves you papers is you priority date no your not penalized it just a long wait of not knowing there is also a date when you sign up for web page that csc recieved your case but dont mean too much my papers were aproved oct 18 and i still havent gotten approval e-mail or web page hasnt been updates

It seems that in practice, you could be penalized for a transfer. NSC received our petition on Oct. 3, but online, the petition was received "on Oct. 24." In addition, we still have not received the NOA, even though I have already done the biometrics today. Seems odd.
