In a further effort to streamline the filing of petitions with lockbox facilities, USCIS has announced the release of a newly revised I-140 form and filing location for Forms I-140. Form I-140 filed alone or together with an Application to Register Permanent Residence or Adjust Status (Form I-485) should be filed at the USCIS Dallas Lockbox facility, or at the USCIS Nebraska or Texas Service Centers, depending on the classification for which the petition is being filed. Forms I-140 for skilled workers (marked "f" in Part 2, Petition Type, of the form) should continue to be submitted to either the Nebraska or to the Texas service centers. Forms I-140 that are accompanied by a Form I-907, Request for Premium Processing Service, should also be submitted only to the Nebraska or Texas service centers. Beginning on August 3, 2010, all other Form I-140s should be submitted to the USCIS Dallas Lockbox facility. Detailed guidance can be found in the updated Form I-140 instructions on the USCIS website at

If a service center receives a Form I-140 that should have been submitted to the USCIS Dallas Lockbox facility, it will forward the form, and any other forms filed in the same envelope, to the Dallas lockbox facility for 45 days (until September 17, 2010). After September 17, 2010, petitions improperly filed at the USCIS Service Centers will be returned to the petitioner as improperly filed, with instructions to send the petition to the correct location. USCIS will issue a receipt upon receiving a properly filed Form I-140 in accordance with its revised filing instructions.
