If you have filed for a Section 333 exemption you’ll be waiting more than 120 days. I filed mine back before Christmas 2015. I have customers waiting for my business Pennsylvania SkyOps to launch so I asked my congressman if he could check on the application. The FAA replied back that they are running at least 150 days or longer because of a huge backlog. They also handle them in the order they come in. So, if you filed after Jan 1 2016 you’re looking at May before they look at your application.
