I filed for a GC through my husband. I am currently on employment authorization (have EAD card) and did biometrics (fingerprinting) a few months back. Th dates for green card processing retrogressed for my country since then.

Recently, I was only cited (not arrested or fingerprinted or photoed) for a misdemeanor that may be dismissed in the court, case pending. Since this incident took place after Biometrics, am I required to inform USCIS and/or fill any additional forms for the pending case OR do I wait until after my FBI background check, USCIS will find out about this charge and ask me for additional documents?

Please advise what must I do? Thx
