USCIS is planning to open a new facility in Elgin, Illinois, next year to expand the lockbox capability.
To prepare for this shift, on Oct. 15 USCIS adjusted the filing locations for some applications. Now, certain adjustment of status applicants submit their applications to the Phoenix Lockbox instead of the Chicago or Dallas Lockbox. Additionally, USCIS has streamlined filing locations for certain employment-based forms to a single lockbox location. You can find the latest filing instructions on the Form I-130, I-131, I-360, I-485, I-601, I-765, I-824, and I-864 pages.
In the coming year, USCIS is planning a few more filing location changes. USCIS will continue to balance incoming volumes by directing some family-based adjustment of status applications to Dallas. Early next year, USCIS will add Elgin as a filing location. Next summer, USCIS will be moving the lockbox facility in Arizona from Phoenix to Tempe.
Applicants who submit their application to an incorrect location may experience delays in processing their case.
