Probably not possible, but one solution would be to close the Southern border to all without legal authorization (visas, work permits) until a satisfactory immigration law is passed. Asylum seekers cannot enter until the law is passed. That will provide motivation to get the job done. The public must also speak out against amnesty.
Anyone caught entering other than a manned crossing needs to be escorted to an official entry point and removed from the US.
Immigration law as it used to be with quotas assigned for each continent and a thorough process for applicants is best.
Anyone who has entered illegally should never be granted citizenship - work permits OK in some cases such as for agricultural jobs, but never citizenship - Illegal entry a disqualifier. That condition alone will keep them out.
That has NEVER worked; something missing MUST be corrected first.
Why else would you have felons deported 26 times?
