USCIS just updated its count of FY2013 cap-subject H-1B petitions.
As of April 13, 2012, USCIS has received approximately 20,600 H-1B cap-subject petitions under the regular H-1B cap (out of a total of 65,000) and an additional 9,700 H-1B petitions for people with advanced degrees.
The H-1B master’s degree quota is almost half gone (it will probably be more than 50% gone by the same time next week). The regular quota is still available, but not for long. Probably will be gone by the summer based on my predictions.
