H-1B visas are still available for fiscal year 2010
This year is very different in terms of the number of people filing for H-1B visas. Last year, USCIS, received enough applications on April 1 such that the cap was reached on the first day applications were accepted. This year, it is a different story.
As of May 4, 2009, USCIS had received 45,000 petitions toward the 65,000 cap limit. Thus it is still possible to file an H-1B petition for a job beginning October 1, 2009. (The government fiscal year begins on October 1.) There is also an additional 20,000 visas available for persons with advanced degrees (a Master's degree or higher). Although USCIS has received 20,000 of these applications, they are still accepting additional applications because it has been their experience that not all of these petitions are approvable.
