USCIS has announced that it has received enough capped H-1B filings to use up the annual cap for fiscal year 2011. Employers and workers must wait until April 1 to file petitions for new H-1B workers to start October 1, 2011.

H-1B or similar filings may continue for cap-exempt situations, including extensions for existing H-1Bs, transfers from other employers, workers employed "at" universities and affiliated or related employers, workers for non-profit or governmental research entities, workers from Australia, Canada, Chile, Mexico or Singapore, doctors who ever received a waiver for work in an underserved area, or workers joining or transferring from employers in Guam or CNMI.
