From USCIS News:
WASHINGTON— On Feb. 21, U.S. Citizenship and Immigration Services (USCIS) began receiving H-2B cap-subject petitions for the second half of fiscal year 2018.
During the first five business days USCIS received approximately 2,700 H-2B cap-subject petitions requesting approximately 47,000 workers, which is more than the number of H-2B visas available. As a result, USCIS, in accordance with applicable regulations, conducted a lottery on Feb. 28 to randomly select enough petitions to meet the cap.
USCIS will reject and return the petitions and associated filing fees to petitioners that were not selected, as well as any cap-subject petitions received after Feb. 27.
