There isn’t a numerical upper limit. A job isn’t property that can be owned and stolen from you. You’re presenting a false dichotomy on top of a false premise. And it’s not goodwill, it’s a matter of principle and ethics.

An immigrant can’t take jobs from citizens, since jobs aren’t property owned by citizens. Jobs are trades (an agreement, a relationship) between two people. Do I really need to explain that a job isn’t an entitlement you get for being a citizen? I think you know this.

No matter how many immigrants come here, they can’t steal the fruits of your labor. Immigrants aren’t reaching into your bank account and taking your money.
