"Department of Homeland Security" or "U.S. Department of Homeland Security" ?

[besthopes 9]

In the link ( http://www.uscis.gov/sites/default/files/files/article/attachments.pdf ) it is mentioned:

You must send the $680.00 fee with your application. Pay the fee with a check or money order drawn on a U.S. bank payable to the

Department of Homeland Security. Do notuse the initials DHS or USDHS.Do Not Send Cash.

Whereas in the link ( http://www.uscis.gov/forms/citizenship-and-naturalization-based-forms/document-checklist-form-n-400-application-naturalization ), it is mentioned:

A check or money order for the application fee and the biometrics services fee for fingerprinting. (Applicants 75 years of age or older are exempted from fingerprinting and the biometrics services fee). Write your A-Number on the back of the check or money order. You may combine the fees into one check or money order. Make your check or money order payable to "U.S. Department of Homeland Security."

I am confused in which name I should write a check: Department of Homeland Security OR U.S. Department of Homeland Security

Please advise. Thank you.
