The will to mobilize these patriots is the only thing holding it back from being the worlds largest army in the mere span of a single heartbeat. If Trump decides to try and deport CCP people in a orderly, civil, gentle but insistent way, and this practically unheard of act of generosity is rebuffed with riots, hostages, violence and worse from these invading insurgents, then he has the option of taking a much tougher and harder stance.

If Trump legally indemnifies all citizens from killing chinese people and issues a 'if you are still in my nation after date DDMMYYYY then you can legally be killed by ANYONE at ANY TIME.' then just watch these people turn, run, dive back into the ocean, and make for their homeland as fast as they can paddle. You might recall other nations that formed a citizen militia empowered to kill drug dealers ended this problem practically overnight, there is no reason it also would not work to stop foreign militants.
