My husband petitioned me for change of status, I have an overstayed visa.I got my working authorization but there were some misinformation/mis communication between us and our lawyer and we thought our schedule for interview is may 9 but its in fact may 8 hence we missed the interview. The lawyer sent a letter to the uscis about what happened but I just saw online that our application is denied. What can we do now? I saw that we can reopen the case. Is my working authorization still valid? I am planning to change lawyer. If you can give me great advice we'll contact you. Thank you.
