According to law it is evident that even with an approved EB-2 case, you have the option to file the I-140 under EB-3 – that's a choice open to you, and no one can dispute it. However, this doesn't mean that your I-140 and PERM are permanently tied to EB-3. What is typically done is filing the I-140 under the category that offers a more advantageous date. For instance, if you are in the EB-2 category and the EB-2 date is more favorable, you would file under EB-2. Conversely, if EB-3 is more beneficial, you would choose that option.
It's important to note that you cannot upgrade from an EB-3 PERM to an EB-2 I-140, but you can downgrade from an EB-2 I-140 to an EB-3 I-140 – or the other way around, downgrading from an EB-2 PERM to an EB-3 I-140.
So, when you have an EB-2 PERM, you have the flexibility to file under either EB-3, EB-2, or both. Importantly, this filing of the I-140 does not terminate your case or prevent you from returning to EB-2 in the future. Thus, there's no compelling reason not to consider filing under EB-3. As for whether it's better to file your case under EB-3 or EB-2, my recommendation would be to file I-140s for both categories – EB-3 I-140 and EB-2 I-140. However, for the I-485, it's advisable to file with EB-3 – that's likely the most suitable course of action.
I STARTED MY EB2 140 CASE WORK WITH RAJIV’S OFFICE AFTER WAITING FOR 2+ YEARS ON MY CURRENT PENDING EB3 140 FILED BY ANOTHER ATTORNEY.I GOT VERY GOOD CASE WORK AND DOCUMENTS REVIEWED BY RAJIV, SUMAN AND MATHEW CHACKO IN DETAIL AND SUGGESTED FOR PORTING AND INTERFILING MY 140’S WITH PENDING 485. MATHEW WAS VERY DETAILED ABOUT REVIEWING MY EXPERIENCE DOCUMENTS AND FINDING OUT THE CHANGES REQUIRED. I WAS ABLE TO GET THE CHANGES DONE AS RECOMMENDED QUICKLY. SUMAN WAS VERY QUICK IN ASSIGNING THE CASE TO ATTORNEY AND ALSO FOR ALL EMAILS FOR ANY CLARIFICATIONS NEEDED. EVEN THE ADMIN STAFF IS QUICK TO RESPONSE WITH SHIPMENTS OR ANY NOTICES. RAJIV WAS SO HELPFUL IN REVIEWING THE CASE IN DETAILS FOR HAVING THE CASE FILING DONE IN A STRATEGIC MANNER ESPECIALLY FOR INTERFILING THE MULTIPLE 140’S I HAVE GOT APPROVED AND PENDING SO FAR. FINALLY WE GOT THE APPROVAL IN LESS THAN 35 DAYS AND I AM REALLY REALLY THANKSFUL FOR RAJIV AND HIS STAFF, ESP. MATHEW CHACKO AND SUMAN FOR THEIR GREAT HELP AND CONCERN TOWARDS THE ATTENTION GIVE TO CLIENTS.I CERTAINLY REFER ANYONE OF MY FRIENDS OR KNOWN PEOPLE TO HAVE REPRESENTATION FROM RAJIV’S LAW OFFICE FOR THEIR GC PROCESS.
