Can I go back to school while my I-485 and I-140 are pending?

As you are being sponsored for permanent residence through employment and have a current H-1B and employment authorization, your going back to business school now may raise doubts as to whether you intend to pursue employment with the sponsoring employer at the time that you receive your permanent residence. I suggest that you continue to work for your employer and perhaps attend business school on a part-time basis.
