Subject: Payment Confirmation for I-20 Application

Dear Admissions Office,

I am writing to confirm that I have successfully submitted the application fee for the issuance of my I-20 document. I have attached the payment receipt for your reference. However, I noticed that after logging in again, the system indicates that I still need to pay the fee again.

Could you please check if there is any error or discrepancy in my application? I have already paid the required fee and I do not want to pay again unnecessarily. Kindly let me know if there is any further action needed from my end.

Thank you for your attention to this matter.

Best regards, [Your Name
