By the end of today, if you haven't filed your H-1B petitions to hire foreign tech workers starting in October, forget about it. U.S. Citizenship and Immigration Services will stop accepting the applications on Wednesday.

On Monday, USCIS received 150,000 petitions for the 65,000 H-1B visas that will be issued for fiscal year 2008, starting Oct. 1.

USCIS began accepting the petitions April 2 -- and although the 150,000 petitions received Monday (not to mention the tens-of-thousands still being counted today) are more than enough to fill the annual allotment, USCIS is mandated to accept the petitions for two days, says a USCIS spokeswoman.

USCIS will begin rejecting petitions for H-1B Wednesday, she says.
