Customer Service Details for INS forms lockbox filing

USCIS collects immigration-related applications and fees through several channels as it’s a self-funded fee-based agency. These include field offices (Service Centers and District and Field Offices), e-filing, and the Lockbox facilities provided through the Department of Treasury.

Direct Mail Program was started in the mid 1980s by the Immigration and Naturalization Service (INS) called USCIS from 2003 through service centers. Works done by INS district offices previously namely handling mail, data entry, fee collection, file, and adjudication operations of most applications and/or petitions for immigration services and benefits were handled. These service centers were not staffed to handle walk in applicants or answer queries.

USCIS has been steadily centralizing intake of forms at their lock box facilities over the past few years. More quickly forms are received and process payments more efficiently and securely in these facilities.

As a recent addition beginning June 4, overseas customers will be able to mail INS forms I-601, Application for Waiver of Grounds of Inadmissibility and Form I-212, Application for Permission to Reapply for Admission into the United States after Deportation or Removal to the Phoenix Lockbox. It’s easy to Mail forms to a USCIS lock box.
