1) Is the interfiling request valid? 2) Will I be asked for an I-140 amendment on I-485 interview?

An employment based I-485 interview after 180 days from filing the I-485 permits an I-485J AC-21 request if in the same or similar I-140 employment.
Is my answer "BEST ANSWER" and/or "HELPFUL"? If so, please acknowledge and mark it so. Mr. Smith has 25 years of successful U.S. immigration law experience with cases just like yours. Still, his response is general in nature, as all the facts are unknown to him, and cannot be construed as legal advice. Please retain immigration counsel to analyze your particular situation in order to receive specific advice. Specific answers requires knowledge of all the pertinent facts of your case. Any answers offered by Mr. Smith on Avvo are of a general nature only, and does not create an attorney-client relationship.
One would need to know more about the situation before opining. You question is presented in way too broad a way.
