When filling out the I-485 AOS it asks for the I-94# and the Nonimmigrant Visa Number but I am not sure where these numbers are located and which one to pick, thanks

Your I-94 is the form given to you at the port of entry, it is the one you filled out on the plane or at the land border on entry to the US.

It is a small white card, smaller than an index card. If you ever got any extension of status or change of status, the I-94 number remains the same. Look at the bottom of your most recent I-797 approval notice, there is a 2-part perforated form, marked I-94. Hope this helps, good luck!

Should be an eleven digit number. Don't confuse it with the receipt number, which has a three letter prefix.
