F-1 EAD last name issues

Hello everyone,
I recently got my i-797C for opt EAD appliaction, my last name’s last letter is missing even though i filled it out on the form, will this cause issues later for my ead processing?will this be a reason for delay?

You should get it fixed to avoid issues in the future. It needs to have the correct details, so that the same details get captured for Payroll, SSN and other aspects. Call USCIS or work with your DSO to get it fixed.
