Are you really suggesting that Corporate Officers aren't able to enter contracts, sue people, etc.? And what the Hell have immigrants got to do with any of this?
Corporate officers are able to enter contracts, sue people, etc, as themselves. Not as the company, which is a separate person from themselves. When you buy a product from Apple and they refuse to respect their warranty, you don't sue Tim Cook, you sue Apple. You can only do that because Apple is incorporated.

You arrest the employees if what they did was criminal (which would be the case whether a company is involved or not) and fine the company, or in extreme cases, revoke the company's charter (aka corporate death penalty).
Being able to be imprisoned is not a defining feature of a legal person, this line of argument will get you nowhere.
