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.
All Readers, I quote from my latest msg. to Mr. Rajiv Khanna's office. Please make yourself more aware on your issues by visiting his web-site (and positively contributing to it) and get advice from his office for your particular needs. All cases are NOT the same. Quote Dear Mr Khanna I barely get time to go to your web-site, though I know it is an ocean of information for all those awaiting their immigration process at some stage or the other. Today I happened to spend an hour there and learnt that your Office had done me good!! I live in an area which lacks Indian neighbors and in my Office too, I am the only Indian working in my whole division! Therefore, there is seldom any interaction with people who are at a similar stage as me in the Immigration process. When my I-140 was filed, your Legal Assistant Nimia Aranibar informed me of the CP option. Though I might have surprised her with my lack of knowledge on this process, she explained the process to me and answered my doubts. And she did as I opted for. No suggestions or implications or other discussion. She was very professional in giving me the information and in answering my questions on the issue. She even understood my concerns with the CP process and offered to clarify my doubts and suggested the recourse to this choice if I needed a recourse at a later date. After reading the chat-site on your web-site, I now realise that the lady was giving me good information at the right time. There are so many people on the web who feel have been un-informed of this process. I, on the contrary, have got the right information from your office and am very happy about this. Thank you and best regards Prateek Rishi Nimia, reading in copy, thank you very much for the time taken to explain me the two processes.
