While the mere fact that the alien is not working for the employer is not sufficient to deny the I-485, it may lead to a rebuttable conclusion that the alien does not intend to work for the sponsoring employer, which certainly is grounds for denial.
This is exactly right. The whole thing about employment immigration is based on sincere intentions. If they suspect that you do not have sincere intention to join the sponsoring employer after PR you may have problems. Remember, the burden of proof is on the alien. They do not have to proof that you do not have sincere intentions. (Just like they do not have to proof that you are not eligible for an immigration benefit, you have to proof the opposite). You have to proof that you DO have sincere intentions. And how do you proof it if you are not working for your sponsor.
It is similar situation when you enter US on visitor visa and then you try to switch to student visa. They can deny F1 because they can suspect "dual intentions" - your coming to US was not with intent only to visit but to study. That is why lawyers advice that you join the sponsor as soon as possible. Of course this does not mean that they will deny your particular case. Just hope for the best.
And of course I am not a lawyer and you do not have to listen to me.
but how do you prove you have real intention of joining your sponsoring employer once PR is obtained?
You said already the burden for the proof is upon the applicant, not CIS. As long as you can prove that you have the intention to join your sponsoring employer once your PR status is obtained through the employer's letter and L?C etc. As long as you are qualified for this job, namely the occupation/position is the same or similar as your current one. You don't need to work for the sponsor in accordance with the immigration law.
What if the applicant is not in the US, but the sponsor agrees to file the labor certificate, I-140 and eventually I-485 by you right after I-140 is approved. You think CIS would deny the case based on the fact that the applicant is not working for his/her sponsor? This is clearly groundless.
To give you an example, a friend of mine who works outside US as a lawyer/legal consulant got PR earlier this year after a long tedious wait PR process. He graduated from NYU as a law student and got sponsor in NYC who applied L/C for him. During this 9 years he never worked for his sponsor before, but he got AOS interviewed in US consulate together with his family and ended up with an approval. If what you said is right, then there is no way for him to get PR because he never worked or at least he was not intended to work for his sponsor in the eyes of CIS...
