回复：I guess you misundertood his question

He asks if he can change job during 485 pending to pharmacist like many medical doctors do. It is up to the company. Some companies have policy not accepting non-green card holders, and some accept. As I know most of hospitals also require green card, but not all. A friend of mine becomes a medical doctor during his 485 pending.

It is up to VO to approve GC, not job offer.

I can see your point here, but change job during 485 pending is also common.
