I second what newdawn said, I would recommend filling the 455 online, it's easy and quick. The majority of people hear back from SSA within a month including myself.
You will get the following confirmation email:
SSA 455 Online Form has been Signed and Filed.
You're done signing SSA 455 Online Form. Open Agreement.
You can open the final document to review its activity history or download a copy for reference.
The agreement is fully executed. The sender of this agreement has control over the retention period for this agreement which determines the amount of time it will be available for download from Adobe Sign. Adobe recommends that you save a local copy of this fully-executed agreement for your records.
Hope that helps!
