United States Citizenship and Immigration Services (“USCIS”) has revised its Form I-129, which employers use to petition for temporary workers in a variety of nonimmigrant visa classifications. The revised version of the form was published on the same day that the final fee rule became effective (November 23, 2010). USCIS will accept previous editions of Form I-129 for 30 days, or until December 22, 2010.

In other words, the last day that USCIS can accept previous editions of the form is December 22, 2010. Petitions must be postmarked or filed on or before this date for the previous edition to be accepted. On or after December 23, 2010, USCIS will only accept the revised form (with the November 23, 2010 revision date) and will reject requests using previous editions of the form. Petitions postmarked or filed on or after this date require the new version of Form I-129.
