A revocation means that an I-140 was initially approved and then subsequently canceled. Therefore, a revocation implies there was an initial approval. If a case has never been approved, it cannot be revoked; it can only be withdrawn or denied.
For example, let's consider a scenario: I, as your employer, file your I-140 application, and if USCIS informs us that they are denying the case due to certain problems, this constitutes a denial. This is a clear and understandable situation. However, if I, as your employer, submit a cancellation request before the case is approved, that is referred to as a withdrawal. On the other hand, if the case is already approved, and I decide to inform USCIS that I wish to cancel it, this is categorized as a revocation.
Another circumstance that leads to revocation is when USCIS has initially approved a case but later issues a notice of intent to revoke the approval. Additionally, if they discover any fraud, this is a grave matter that should not be overlooked, as it carries criminal implications and can result in a permanent bar for the employee from entering the US.
In summary, when a case is approved and subsequently canceled, whether by the employer or the government, it is considered a revocation. However, if the case is still pending, the only options are withdrawal or denial.
Rajiv and Diane are the best immigration lawyers I've worked with in my 12 years in the US, across the several firms I've worked with over the years. I worked with them on my O-1 visa. Processing timeline delays with my PERM application nearly threatened my work authorization in the US. Rajiv and Diane worked on a tight timeline expeditiously not only to get my O-1 visa approved but also to get my green card approved, all within 6 months. This is the fastest timeline I have seen - they are a great team!
