Hi! We received our I-751 application package back from USCIS. The letter said we sent the wrong payment amount. Isn’t the payment $680? $595 application fee + $85 for biometrics. What am I missing? Also, we paid with credit card, should we have sent a check instead?
Lastly the application and all other documents, now have some codes and markings at the bottom of the forms, can we resend those same documents back or do we need to print new copies of everything?
