I have filed the adjust of status through my employer based on EB3. Change of status was denied recently with the reason of not maintaining the non-immigration status (F1). I was in OPT when I was granted first TPS in 2015. I applied for the OPT extension and it was approved as well. After the completion of OPT (2017), I have been working under TPS and never admitted to school.
Recently my employer filed the I-485 and I attended the interview as well. After few months of interview, I received a denial for not lawfully maintaining F1 status. Have any one been in similar situation before? Have any one has approved i-485 from TPS? Is there any attorney that can help on this ?

On the same boat, waiting for interview for AOS based on DV lottery. Biometrics got waived.
