I understand that if a person's I140 gets approved and 485 has been pending for 180 days, he/she can change employer provided the job is similar to what the labor was approved for.
1) Are the 180 days of I485 pending counted after the approval of I140?
2) Can the employer who sponsored GC, revoke the I140 after the person changes the employer making use of AC21?
