The United States Citizenship and Immigration Service (USCIS) has announced that several more forms will be transitioning from the Service Centers to the Lockbox Network. USCIS believes that by centralizing form and fee intake to a Lockbox environment, USCIS will improve consistency and integrity in the intake process.
The forms scheduled for the transition include:
I-140, Immigrant Petition for Alien Worker;
I-129F, Petition for Alien Fiance;
I-539, Application to Extend/Change Nonimmigrant Status (Only those filed separately from the I-129)
I-526, Immigrant Petition by Alien Entrepreneur;
I-817, Application for Family Unity Benefits (If filing under section 301 of the Immigration Act of 1990)
This transition has already started, as the Service Centers will be forwarding applications to the appropriate Lockbox facilities. USCIS plans to announce the address change sometime in June and will revise the filing instructions and update the web page for each form.
