my I140 got filed almost 4 weeks ago under regular processing, I havent received receipt notice yet
I want to upgrade to premium processing
do I have to wait for receipt notice or can I do right away?
It's called Receipt Number. This one is assigned to each case when they receive your application.
Also, if you have a file with USCIS already or an online account, you can use your beneficiary number, which is unique. Without either of those, you will only have your identity as a reference, which will make it difficult.
If you have the reference number for your first filling, then you can do it right away.
Thanks! whats this reference number called?
