My status on uscis.gov is shown as "Additional Documents Requested Letter Sent on 13 May". I had not submitted my transcript while applying for H1B. Now I want to know that what are my chances of getting H1B approved if I submit my transcript now. As I have not received the letter sent by USCIS yet, as it was sent on 13 May only.

I am just curious to know that do they ask for additional documents for everybody who has not submitted transcript?

Thanks
