On August 28, 2018, USCIS announced that premium processing will continue to be suspended for FY2019 H-1B cap (lottery) cases and in addition, starting September 11, 2018, premium processing will be suspended for H-1B portability (change of employer) petitions. These suspensions are predicted to remain in effect until February 19, 2019. Note that due to the increase in RFEs for H-1B cases and an increased rate of denials, it is possible that some new hires who are transferring from another H-1B employer will be unwilling to “port” before the change-of-employer petition has been approved by USCIS. This could cause delays in on-boarding.
Note that Premium Processing continues to be available for H-1B extension petitions for continuation of the same position with the same employer, and for employers who are exempt from the H-1B cap, such as universities and non-profit research institutions.
