Desp123,
I think you can try to get the I-140 reciept # info by calling the national service center 1-800 number, I am not sure !!!. Tell them that you have applied for I-140, I-485, EAD and AP, and you have reciept #'s for all the cases except I-140 and would like to know status of the application. Also tell them that your AP is still not approved, etc.. Then they may ask your details like your name, employer name, other case reciept #, etc to locate your I-140 case #. also, as naanshi poited out, your A# in your I-485 reciept is the key, it is same # in both I-140 and I-485, and you can tell this # to the person.
If you cannot get theI-140 reciept # from your first try , try calling again and again to the 1-800, because each person who answers your call has his/her own way of answering your request, and someone will help you. Try to be very very friendly and ask..
For now try to maintain a good relationship with your employer, because I think your I-140 is very close to approval.. I am seeing lots of approvals for I-140 for Aug 2003 in my scanner for last 2 weeks.
Once you come to know that your I-140 is approved then you can forget him as your 180 days have completed, but if there is any RFE on I-140, then your employer is the only one who can help you out..
