Submission + - U.S. to Temporarily Suspend Expediting for H-1B Visas (uscis.gov) 1
Starting April 3, 2017, USCIS will temporarily suspend premium processing for all H-1B petitions. This suspension may last up to 6 months. While H-1B premium processing is suspended, petitioners will not be able to file Form I-907, Request for Premium Processing Service for a Form I-129, Petition for a Nonimmigrant Worker which requests the H-1B nonimmigrant classification. We will notify the public before resuming premium processing for H-1B petitions.
While the ostensible reason given for this suspension is to "help us to reduce overall H-1B processing times," there is little doubt that this move is tied to President Trump's ongoing efforts to curb abuses in the controversial H-1B program.
