USCIS has received enough H-1B petitions to meet both the regular 65,000 cap and the 20,000 master's degree cap. CIS did not say exactly how many petitions were received, USCIS has suggested that the number is lower than last year's 236,000 petitions.
The agency did not say when it will conduct the lottery but, if they follow last year's timing, it could be this week.
