CSPA- Priority Date

[immihelp]

The information on our web site is correct.

I am not sure what exactly your question is.

As per site

https://www.immihelp.com/immigrant-visa-number-priority-date/

it says
If you have filed for alien labor certification, then your priority date is the
date on which your application was recieved by the state level agency(SESA).If
instead of labor certificate, you are going through the N1W/Eb1 route, then your
priority date is the date I-140 petition was received by USCIS

It means for EB3 , one should take Priority Date not in I-140 receipt date
Some site says it should be duration of I-140 only

Can any one please advice
Thanks
