Question: Schedule A Documentation after Position Closed

Hi r/USAjobs!

I have a question about Schedule A:

I found a GS-13 position last week that felt like it was written for me. I have always wanted to break in to the government sector but didn't know how to "crack the code" until I spent days researching and then revamping my application materials to best position myself. Thank you so much to those who contributed to the fantastic Wiki page! 🙌

The job did specify that they give consideration to Schedule A applicants, which I do qualify for, but the application was only open for 7-days (closed last night), and my doctor unfortunately missed the deadline to send me my letter and I just received it this afternoon. I went ahead and submitted my application before it closed without checking the disability box or attaching my letter. I felt like I couldn't pass up the chance even though my odds are now a bit worse.

So my question for this sub is - can I do anything to modify my application to include my Schedule A letter after the requisition is closed? Is there a way to contact the recruiter or am I SOL?

I go back and forth between feeling very confident about my skills and background to questioning if I will even make the referral list. That was compounded even more when I checked my application this AM and saw they had 925 applicants for the position I applied for. Right now I am "cautiously optimistic".

Thank you for your guidance!
