Gary Johnson for President!

The Libertarian-flavored immigration policy that makes the most sense to me is "end (drastically prune) the welfare state, then we can talk about immigration." Remove the perverse incentives, and them as still wanna immigrate are people you'd probably really like to have around, by and large.

[Aesop]

We needn't do mass deportations. Ever.

1) Build the goddam wall, from San Diego to Brownsville. Crossers to be shot on sight.
2) Every one you catch here incidentally, from felonies to broken tail lights, gets 25 years in the federal pen at hard labor, followed by irrevocable lifetime deportation. (Forehead tattooing or branding optional, but heartily encouraged.)
3) Every company caught with 1-5 illegal alien employees gets fined $1M@; any company with 6 or more gets seized bottom-to-top under the RICO statutes, and the CEO and CFO frog-marched into federal court, and out to the federal prison system. Then you seize all their personal assets, houses, chattels, etc. down to their underpants.
4) Then you start doing random employee audits in every city. Monday would be companies starting with the letter "A" in the phone book, Tuesday would be "B", etc.
5) Before you got to "C" on Wednesaday, the line south on the interstates would be backed up to 37 degrees north latitude across half the country with returning illegals.
6) Anyone caught here after their first deportation would be exiled to permanent residence on some modern hellhole of an island modeled upon the Chateu D'If, never to be returned. Alternatively, converting a former Nimitz-class carrier to the world's largest oar-rowed containership galley would provide them with employment for the rest of their lifetimes - as propulsion.
7) Anchor babies can stay or go, but there will be no new Manzanars for legal American citizens, despite the skewed current misinterpretation of US law; but their illegal alien mommies and daddies have to leave, or face the penalties above.
8) Ban all legal immigration of everyone over the age of 50 unless they first post Some Ridiculous Amount Of Cash subject to forfeiture if they don't get a paying job and pay into the social security welfare pot for a minimum of 20 years before being eligible to retire and collect benefits. Scale the amount upwards for each year of age beyond 50. Anyone without at least $1M cash and over the age of 60 needn't bother.
9) Scrap the 1965 Immigration Act entirely, and subject all future immigration solely to two tests: English fluency, and necessity/superiority of possessed skills/trades.
E.g.: The quota for prior criminal behavior would be set at zero, in perpetuity; the quota for illiterate fruit (or ass) pickers would be set at not less than 2 and not more than 4 persons, annually, in total from all countries of origin, henceforth. Quota slots for anyone not fluent in English and with less than a GED or equivalent would be awarded based on number of years of unblemished US military service successfully completed.
If necessary, form and organize a US-officered Foreign Legion for the purpose, which would be assigned expeditionary duty in every shitty little foreign hellhole seen necessary to advance US policy. Need someone to march into Pakistan and slaughter every unrepentant Islamofanatic at bayonet-point? Need to conquer North Korea and scour the last living thing there larger than a housecat from the face of the planet?
"Legionnaires, UP!"

Libertarianism applies only to citizens.
Crooks get treated like crooks.
If the Libertarian Party can't get behind that little, they're simply slow-motion anarchists by another name.
