Hi
I don't think the FSW program opened on May 1st, new caps were put in place to allow CIC to prepare for the Express Entry system starting in January 2015, see below from the CIC site. I just think they are slow, current CIC processing times (as per their web page) is indicating up to 13 months. However we know processing times can be shorter.
Note: As of May 1, 2014, there is an overall cap of 25,500 for new federal skilled worker applications. This includes a cap of 500 applications from PhD students. There are also sub-caps of 1,000 for each of the 50 eligible occupations. The caps do not affect people with a valid job offer. These are the last applications we will accept under the current system before Express Entry launches in January 2015
