To ensure your filing is not rejected for incorrect fees, always check that the submitted payment matches the required fees listed on the Filing Fees page. For forms such as I-129, I-129CW, and I-140, the fees vary based on your status as a nonprofit or small employer. Specific questions in the forms determine the applicable fee category. Submitting incorrect fees, even by overpayment, will lead to rejection. For nonprofits and small employers, ensure your submission aligns with the employee count and status indicated on your form. Failure to accurately demonstrate your status through proper documentation can also lead to rejection.
