Student forget self attestation on I-20

Hi foks,

Currently I am on H4 visa and studying in community college. For further study I have applied for COS from USA. And converting from H4 to F1. My H4 is valid till Mar-2021. Also I am turning into 21yr in Mar-2021.

I got RFE on my F1 application. They asked me to re-submit my I-20 document as my I-20 date was Mar-2020 as per my previous H4 visa… I send them USCIS notice and I-20 document through USPS. But I missed to do self attestion of I-20.

How I can fix this issue in Covid-19 situation?

USCIS may send an RFE again if they need your signature.

Thank you for your input.
