Friday, April 6th, 2018, USCIS announced that it reached the FY 2019 H-1B cap during the mandatory first five business days that the program must remain open to accept filings. USCIS did not announce when it will run the lottery, and SPS Immigration will keep you appraised as USCIS continues to announce advances in its lottery process.
