We were called upon to correct a situation. USCIS sent an RFE stating that the degree and field of study did not match with the labor certification requirements. The I-140 beneficiary had a degree in agricultural science. The employer's requirement in the labor certification was a BS degree in Computer Science, Engineering, and Mathematics.
We were hired to respond to an RFE. Client filed an EB2 I-140, where the PERM Petition required a Bachelor's and 5 years of experience. The client received an RFE in which USCIS argued the Beneficiary's degree, a Bachelor's in Commerce from India, equates to a 3-year degree and cannot be considered for an EB2 case. The Beneficiary possessed a four year Bachelor's Degree, however, this was not clearly established on his Degree. The client obtained his BS in Commerce before India switched to a standard 3-year program for his particular degree.
A beneficiary had two three-year bachelor degrees from India and consequently his I-140 petition was denied on the grounds that the beneficiary did not have a four-year bachelor's degree. We were retained after the denial. Our firm was successful in appealing and winning in less than one month. Of course, this case had unique facts. We cannot assume that all three-year degree cases will go trough this smoothly.
We discussed: Working concurrently with H-1 cap exempt and quota employers, immigration issues if we have a special needs (cerebral palsy) child, applied B-2 to main status while F-1 is expiring, Section 245(k) and illegal work, DETAILED DISCUSSION OF I-140 REVOCATION IMPLICATIONS INCLUDING AC21, impact on H-1 of reentry on advance parole, Section 13 green card for diplomats, who can co-sponsor affidavit of support I-864, proving cross chargeability, transfer of priority dates for a future job approval
An I-140 petition, or Immigrant Petition for Alien Worker, is filed to petition an alien worker to become a permanent resident in the United States. The employer must file an I-140 Petition on your behalf within 180 days from the date your Labor Certification is approved by the U. S. Department of Labor. An I-140 Petition may be filed without a Labor Certification where the beneficiary qualifies under EB-1 classification.

I have finished my first review of H-4 EAD Regulations (effective 26 May 2015). Here are the takeaway points:
This entry is now old law. The new law is at http://www.immigration.com/blogs/i-140-ead-regulations-effective-17-jan…
5 November 2015: After some flip flops, USCIS has gone back to allowing carry forward of priority dates even if I-140 is revoked by employer - as described in this discussion. So, we are good for now.
In a recent meeting, Nebraska Service Center has clarified why, some times, in cases of pending I-485 applications, USCIS approves AOS interchanging the applications of the derivative and principal applicant:
Based on many posts by users of these boards, I’ve decided to write-up a fairly comprehensive posting regarding ability to pay issues and how to overcome RFE’s, Denials and appeals.
Background:
Law governing ability to pay – 8 CFR 204.5(g)(2)
USCIS recently began transferring some Form I-130, Petition for Alien Relative, cases filed by lawful permanent residents for their eligible family members from the Vermont Service Center to the California Service Center.
If your case was transferred, USCIS will send you a notice listing the transfer date and where your case will be processed. Your original receipt number will not change and this will not delay the processing of your cases except for the additional time needed to transfer the file.

My I-140 was filed in February 2004. The National Visa Centre, in its letter dated 24th June 2010, informed that they had completed processing of my petition seeking immigration to the USA and had forwarded it to the American Embassy/Consulate at New Delhi. I was informed that an immigrant visa interview had been scheduled at the US Consulate, New Delhi on the 9th of August, 2010 at 10.45 am.

Please note, for now (June 2008), premium processing is only available if you meet ALL of the current requirements:
1. Your are currently on H-1;
2. Your H-1 status is expiring within 60 days when you apply for I-140 premium processing; and
3. You are not eligible to receive 1-year H-1 extensions because your labor certification was filed less than one year ago.
A beneficiary obtained an RFE given that she underwent only seven semesters for her bachelor's degree, one semester short of the four years typically required. Our office was able to succeed with the RFE and her EB-2 I-140 petition was granted within four days time.
