EAD with family-based petition

[JoeF]

An EAD allows you to work for any employer, be self-employed, etc. Period.
What you refer to is the issue with the underlying I-485 for employment-based GC cases. While the EAD allows to work for any employer, somebody with a pending employment-based I-485 has to continue to work for the sponsoring employer. The person could of course use the EAD to work for somebody else in addition.

My EAD approval notice came yesterday (yea!). I had submitted my family-based petition (married a U.S. citizen) on Sep 3rd at the DC office (Arlington). Currently, I am working on a H1B visa but would like to change jobs, and maybe even get two!

Is it true that the family-based EAD allows me to work for any company, be it on contract basis, full-time, or part-time? In other words, can I cancel my H1 with my current employer and look for other positions? The reason I'm asking is because for employment-based EAD, the person has to work for the sponsoring employer, correct?

Thanks for helping me out!
