Hi Sm1smom, I was about to send my AOS package, but I just realized that I never got my 2nd NL from KCC. What I got from KCC was an email with an attachment saying "Dear .... Thank you for informing us that you plan to apply for adjustment of status with U.S. Citizenship and Immigration Services (USCIS)." I thought this was the 2nd NL, but I realized it was not when I googled how this letter is supposed to look like. I think the reason I got that email was because initially I was planning to do CP at my home country, but since I moved to the US recently under F1 visa, I requested to change the process to AOS instead.
Just fyi, I've paid $330 fee and received a receipt sent via email. Do you think something is wrong in the process? Can I send my AOS package without the 2nd NL? My CN is current (2017AS00003xxx). Thank you!
