A National Interest Waiver (“NIW”) is very desirable as it waives the requirement of a US job offer and labor certification, cutting off much of the visa application processing time. However, NIWs are not just granted to any applicant. When applying under an NIW for an employment-based visa, you must produce at least 3 of the criteria under the exceptional ability standard and prove that it is in the national interest that you work permanently in the US.
