Make the money order payable to U.S. Department of Homeland Security. Use this form to replace your Green Card.A filing fee is required for many immigration forms. If you do not submit the correct fee, we will reject your form. To fill out the money order, you will need to "Pay to" U.S. Department of Homeland Security. The 'Pay to the order of' line should say 'US Department of Homeland Security' and the memo should say something like 'I-751 application and biometrics'. You may download and print forms for free from the All Forms page. Please be sure to carefully read and follow the form filing instructions. As long as the US Department of Homeland Security is the payee, USCIS does not care what address you put on the money order. Very rarely am I motivated to write a review, but I must say the staff at USCIS are the nicest lot!
