Transition Period for Streamlining N-Form Processing Ends Dec. 2, 2011
On Oct. 19, 2011, a USCIS Update was issued announcing processing improvements for certain naturalization and citizenship forms. USCIS has centralized intake of Forms N-336, N-600 and N-600K to the Phoenix Lockbox facility. The Dallas Lockbox facility will handle the Form N-300. This change streamlines the way forms are processed, accelerates the collection and deposit of fees and improves the consistency of our intake process.
This is a reminder that impacted forms received at local and district offices after Dec. 2, 2011, will no longer be forwarded to the appropriate USCIS Lockbox facility. Beginning Dec. 5, impacted forms received locally will be returned to the individual with instructions on how to re-file at a designated USCIS Lockbox facility.
USCIS has updated the information on our N-Form Web pages regarding filing forms at a Lockbox to clearly identify this change in procedure. Please carefully read the form instructions before filing your form to ensure that you are filing the correct form type and edition at the correct location.
