I worked for a Consulting Company A from Apr, 2006 - Dec,2008. My GC was filed/sponsored by A in Sep,2006. After Dec 2008, A did not have any project/assignment for me. So we parted on good terms. Since then I changed jobs 3 times.

Currently I am working for Company B since Mar,2011. Salary and Job description is similar to when GC was filed (Software Developer). I never mailed any AC21 notification to USCIS. Now I just recieved my I-485 approval & Welcome notice.

Q1: Can I continue working for B, or do I have to make myself available to A ?

Q2: If I make myself available to A, can I work in a different role than what is mentioned in my Labor (when GC was filed) ? For example, can I work for A as a "Business Analyst" instead of "Software Developer" ?

Thanks a lot!
