USCIS announced this today.

Beginning July 13, 2015, USCIS will resume accepting Form I-907, Request for Premium Processing Service for all Form I-129, Petition for a Nonimmigrant Worker, H-1B extension of stay petitions. Premium processing requests for Form I-129 H-1B extension of stay petitions received by USCIS before July 13, 2015 will be rejected.

We previously announced on May 19, 2015, that premium processing service would be suspended for Form I-129 H-1B extension of stay petitions from May 26, 2015 to July 27, 2015. The temporary suspension allowed us to implement the Employment Authorization for Certain H-4 Dependent Spouses final rule in a timely manner and begin adjudication of applications for employment authorization filed by H-4 nonimmigrants under the new regulation. Premium processing remained available for all other types of Form I-129 H-1B petitions during the temporary suspension.

We have closely monitored our workloads and have determined that we can resume premium processing service for H-1B extension of stay petitions on July 13, 2015.

As a reminder, we will accept only the new version (edition date: 01/29/2015) of Form I-907. You can find the edition date printed on the bottom left corner of every page of the form and instructions. We will reject previous editions of this form.
