As of June 4, 2012, applicants for immigrant visas can file Form I601 by mailing it with supporting documentation to locations in the United States. Previously, applicants had to submit Form I601 to U.S. Embassies or Consulates or USCIS co-offices located with U.S. Consulates or Embassies. There are United States Citizenship and Immigration Services (USCIS) Lockboxes in Chicago, IL; Phoenix, AZ; Dallas, TX; and St Albans, VT. An applicant is assigned to a particular Lockbox according to his or her circumstances. Check the instructions for Form I601 to determine the Lockbox to which you should send paperwork.
A USCIS Lockbox is a secure facility operated by the U.S. Department of Treasury. A financial agent at the Lockbox collects applications and fees. He or she then forwards the information and money to USCIS service centers. I601 forms are currently being adjudicated by the Nebraska Service Center (NSC). After USCIS processes the applications, the financial agent generates acceptance and rejection notices to applicants. The financial agent at the Lockbox does not make the decision to approve or deny a petition or application.
Assemble a I601 package sent by direct mail to a USCIS Lockbox in the following order: 1) check or money order made out to the U.S. Department of Homeland Security; 2) Form G-1145, Request for e-Notification, if applicable; 3) Form G-28, Notice of Entry of Appearance as Attorney or Accredited Representative, if applicable; 4) I601 form; and 5) supporting documentation. Mark the envelope and cover letter as to the nature of the submission and the form type. Avoid sending originals and keep copies of all submissions.
