Just thought this may give others an idea on I290B. Our I290B was filed on 1/21/25, got approved or per say received the information letter telling us my mom's I485 is re-opened.
Our I290B was for reconsideration with the new I864 fanicial sponsorship info. It seems right on processing timeline about 3month ish. Thought it might be delayed due to many GOV/ICE activities.
Good luck to you too.
