The Form I-129 has been revised by the United States Immigration and Citizenship Service (USICIS) which allows employers to petition for temporary workers under a variety of nonimmigrant visa classifications. Publication of the revisions by USCIS will be available on November 23, 2010.
For 30 days after the publication of the new version or until December 21, 2010, USCIS will accept previous versions of the Form I-129.
Beginning December 22, 2010, USCIS will only be accepting the revised Form I-129 and will decline any request filed with previous versions of the form.
