We filed an I-140 application in which the beneficiary was no longer working for the employer and was living outside the U.S. We included fairly standard supporting documents. To show the employer’s ability to pay the offered wage, we submitted federal tax returns and a W-2 from the preceding year. To show the beneficiary’s qualifications, we submitted a copy of his degree and affidavits from previous supervisors and co-workers with supporting documents.

Please note, for now (June 2008), premium processing is only available if you meet ALL of the current requirements:
1. Your are currently on H-1;
2. Your H-1 status is expiring within 60 days when you apply for I-140 premium processing; and
3. You are not eligible to receive 1-year H-1 extensions because your labor certification was filed less than one year ago.
