For the first time in several years the H1B visa programme, once the most sought after among Indian professionals, is unlikely to reach its cap of 65,000 before the start of the 2010 fiscal with nearly 20,000 slots lying vacant thanks to the tattered US economy.

The US Citizenship and Immigration Services said it has received approximately 49,000 H1B petitions till August seven counting toward the Congressionally-mandated 65,000 cap, more than four months after it started accepting applications for visas for the 2010 fiscal beginning this October.
