To use AC21, one and only one safe way is :
work for the employer over 180 days, change to (or laid off and find) a similiar job, file letter to INS, INS adjudicates the case based the new job.
Other scenerios will have problem in the future.
A. never inform INS job change, the case is approved
B. no job when case is approved, soon find a new similiar job.
c. never work the sponsor company(future job), case pending is over 180 days and approved
.........................
all the above cases have the material mispresentation problem.
It's your responsibility to inform INS your employment change.
Otherwise, INS can revoke your GC in the future.
