U.S. Citizenship and Immigration Services (USCIS) is announcing the implementation of the H-1B registration process for H-1B cap-subject petitions. The initial H-1B petition registration period will begin on March 1, 2020. Starting on that date, USCIS will require H-1B cap-subject petitioners, including those eligible for the advanced degree exemption, to first register electronically with USCIS and pay the associated H-1B registration fee before being eligible to properly file an H-1B cap-subject petition for the Fiscal Year 2021 H-1B numerical allocations. USCIS intends to close the initial registration period on March 20, 2020 and will announce the actual end date on its website. After the initial registration period closes, USCIS will conduct the initial selection process, and petitioners with selected registrations will be eligible to file an H-1B cap-subject petition for those selected registrations during the associated filing period.
