Can someone walk me through how to request an SF-50? I know I am going to need one for the next bid. I am no longer an FAA employee and I need to be able to show proof of my ATC experience. I was told I need to contact OPM to request it but I am yet to get a human to answer the phone. I have also heard it needs to be a written request over mail. Can someone give me a little more guidance on how to request the SF-50? Thanks.
