Please help!!! Confused

[anandsbr]

I have recently got EAD but not used it. Means am still H1. I am getting good offer from my client company. I have filed my labour on EB3 somewhere in 2000 and got approved. I have I-140 approved too in 2002. I have been with the same employer for 4 years. Now i want to join this big company. In this company, Techincal skills are entirely different as well name of the designation. but duties are the same.

I do not know what is mentioned in Labour and don't have a copy of it. but I have 140 approval notice.

Under this situation what I should need from my new company's HR dept in order to invoke AC21?? Do I need to consult a lawyer or should I wait for RFE and then react?

------------youare eligible for AC21
I have been with the same employer for 4 years. Now i want to join this big company. In this company, Techincal skills are entirely different as well name of the designation. but duties are the same.
------------- the office who is going to approve your I-485 has your LC, I-140 in the file and going to look at if your new job offer letter and job duties, job duties should be same/similar on new permanent job offer letter
I do not know what is mentioned in Labour and don't have a copy of it. but I have 140 approval notice.
---------------- if possible try to get approved LC copy particularly form EATA750A and in item 13 are your job duties
Under this situation what I should need from my new company's HR dept in order to invoke AC21??
------------ Perment job offer letter with same/similar job duties
Do I need to consult a lawyer or should I wait for RFE and then react?
------------ that is upto you, I will update USCIS and send request to invoke AC21 with new employer job offer letter+I-485 filing reciept copy. why I give them chance to send RFE and again i have to reply RFE and delay in processing??
