Then you should wait until the I-140 has been approved and the I-485 has been pending 6 months before leaving.

I appreciate your prompt response and help.

Why having to wait? You can file 140 and 485 concurrently

[sadlion]

The i485 depends on i140 being approved and requires more lawyer fees and prep. If you concurrently file and i140 gets denied, the employers have to swallow the cost. By having me pay for premium processing for i140, they minimize their cost without significantly affecting waiting time.
