In a surprise to no one, USCISannounced today that it has reached the H-1B cap for both the regular and master’scap.  The USCIS is expected to hold anH-1B lottery within the next week. 
If your H-1B petition is filed underthe Premium Processing Service (PPS) you should hear of its acceptance no laterthan April 28.  However if your PPS petitionis not accepted, it may take until mid-May before you find out that the casewas not accepted under the H-1B lottery. 
Reminder:  The PPS does not give a petitioner anygreater chance at winning the H-1B lottery, but it does allow for speediernotice and decision-making.
If your H-1B petition is filed underthe Regular Processing path it may be until May or even June before your findout if your H-1B petition is accepted under the lottery or not.  Last year it took about 10 weeks before allH-1B petitioners were notified of their acceptance or rejection.
