Today the United States Citizenship and Immigration Service (USCIS) announced that they did not receive a sufficient number of lottery submissions in the March 2021 lottery to meet the annual H-1B quota and, have thus, run a second H-1B lottery of the electronic registrations previously submitted. The filing window for newly selected petitions will be between August 2, 2021 and November 3, 2021.
Unfortunately at present there is a glitch in the myUSCIS website wherein, currently, only employers are able to log in and check on the registration status. The glitch is widespread (impacting all attorney accounts) and the immigration bar is already working with USCIS to get it resolved. In the meantime the company should be able to log into their myUSCIS to gain access to the newly selected cases and can forward those to immigration counsel for further action while USCIS resolves the website glitch.\
UPDATE: USCIS has resolved the attorney access issue and attorneys should not be able to log into their myUSCIS accounts to check on selected registrations.
