@Kentavar2397 hi guys, my field office is also Los Angeles. Based on my knowledge, our cases will be done in the LA District Office, not the LA County office. When you google Los Angeles USCIS Field Office, the address gives you a room number of 7631. On the interview letter, it should have a different Room number even if the street address is the same. Again, don't count me on that, but based on my knowledge, we will be able to attend to our interview successfully even if the LA Field Office looks closed on their website. Unless we get a call back as Kentavar2397 did for his bio appointment.
