Hi there, I submit i589 in March 5 2021, didn't get a biometrics letter so far, but my status change to next step is interview, is that normal? Is there a way to know whether they have sent my biometrics letter or they're still scheduling it? I am not sure who to ask, the SF asylum office or the ASC center around my address? How long should I wait before I contact with them for the biometrics letter?
