USCIS received 190,098 H-1B petitions this year during the first five business days,
about 9,000 cases less than last year. Visa lottery has been completed too as of 04/12/2018. Notifications will be sent out gradually. Receipt notices will be mailed out first to the lucky winners, and unselected cases will be returned later on. Applicants should not lose hope until the end as it will take weeks for USCIS to process and send out all filing receipt notices.
