The foreign-born populace is the natural place to start in any attempt to repatriate recent immigrants and their descendants from Texas. 58.3% of immigrants in the state do not have US citizenship, and are therefore easily removed. Cancelling the visas, enforcing immigration law, and revoking green cards of these non-citizens would enable the removal of some three million people, 84% of whom would be Hispanic and Asian. 1.6 million of these individuals would also be illegal aliens in the state (there are many more illegal aliens in Texas as we have written about here or here, but we are using official statistics for this piece).
On the tail of these adult immigrant departures would be the departure of their children. We take a strong stance against family separation and maintains that immigrants who leave the United States must take their under age children with them. This policy would see up to 2.4 million additional people depart Texas.
Simply enforcing immigration law, and refusing to renew visas or green cards would see up to 5.2 million people depart Texas and would increase the White Texan population from 39.7% to 47% of the state’s overall population. All without stripping a single person of their American citizenship.
With illegal aliens, resident aliens and non-US citizens out of the way this brings us to the very large minority population in the state which is in possession of a US passport. The most efficient method to deal with this population is through mandatory review of their citizenship and immigration paperwork, specifically in the realm of family reunification.
70% of immigrants in the United States are admitted on the basis of family ties, not for work or school. This means that a large portion of people who have acquired US citizenship are likely to have done so fraudulently. The proof for this is best demonstrated by a 2008 incident wherein the US State Department discovered, through DNA testing, that over 80% of individuals admitted into the US as a family member of a “refugee” were not related to that individual. The US government has since mandated DNA testing for refugees who request their family members come to the US, but this DNA testing mandate has not been put in place for any other category of family reunification.
By simply requiring proof that immigrants are related through marriage and birth certificates, and yes DNA testing, it is likely that more than half of naturalized US citizens in Texas, and the nation as a whole, could have their citizenship revoked on the grounds of fraud. Citizenship can also be revoked on the grounds of felonies committed before a person becomes naturalized.
This process could, assuming generously low fraud rate of just 65% (and in all likelihood the fraud rate is closer to the aforementioned 80%), result in 1.4 million naturalized immigrants in the state of Texas losing their US citizenship and being removed from the state and the nation. This brings the repatriation total up to some 6.6 million people. This combination of policies would restore the Historic Texan population to majority status (just barely) and only when using official statistics.
