@NepalUsaXXX: I think most likely it depends on USCIS as well as ombudsman. I applied for EAD on february and TPS on August. Applied ombudsman on february same time i applied for EAD and it took them almost 3 months to find out that both my cases being approved. 3 month or 90 days is the time they should be approving and as i said before this august can be a lucky month for you.
