USCIS Transitions Filing Locations to Lockbox FacilitiesTo provide a more efficient and effective initial processing of applications and fees, USCIS is transitioning the intake of additional forms from USCIS Service Centers to USCIS Lockbox facilities. Centralizing form and fee intake allows USCIS to utilize the Lockbox facilities technology to put your application into our system. The filing locations for the following forms have been changed: - I-129F
- I-130
- I-140
- I-526
- I-539
- I-817
