Hey, new update! The letter was in fact a scam to get me to sign up for the identity theft protection and phish details from me there. Thank you to everyone in the forum for taking the situation so seriously though, I appreciate the encouragement and suggestions. Stay safe out there! I thought I was smarter than this, but it's so simple to be tricked when emotions are high. I found out by visiting the LA Field Office (where the letter still fooled multiple USCIS employees) and it was ultimately a security guard who pointed out a number of errors within the letter.
