Per OMA Connections Partner, Dinsmore, April 3, 2017 is the first day on which U.S. Citizenship and Immigration Services (USCIS) may accept H-1B specialty worker petitions for the next fiscal year beginning on October 1, 2017.
Due to the overwhelming demand for the annual allotment of 85,000 new H-1B slots, employers who wish to file new H-1B petitions for current or future employees should do so on April 3rd. The number of H-1B approvals requested by employers has reached the annual H-1B cap every year for more than 10 years. Last year, USCIS received 236,000 petitions within the first week, then conducted a random lottery to determine which petitions would garner the 85,000 slots.
