Right off the top of my head it’d look something like this.
I’d start with the wall. I’d also provide additional resources (money, equipment, and personnel) to I.C.E.
All immigrants attempting to cross illegally from this point forward would be placed on a barment list, deported immediately, and no longer illegible to enter our country. My thoughts on this is if you’re willing to break our laws getting in then you obviously have no regard for our law.
I would require all personnel seeking asylum to register through our embassies with an expedited review process. All personnel seeking asylum would be vetted for criminal or terrorist affiliations and disqualified from entry if found during our review. If individuals showed up at the border, they would be denied entry and treated as illegal immigrants unless they had registered and been vetted at the embassies. If already registered, they would be placed in hold facilities in categories (families, men, women, children) and giving their hearing. If denied, they’d be deported immediately. If approved, I would allow them entry on an approved visitor Visa for up to 5 years. During that time they would be required to learn the English language, assimulate within our society, and at the end become a legal immigrants. If they did not meet the conditions, be it their failure to meet the conditions or they were convicted of a crime, they (to include family members) would be deported. If by chance a family entered and had separated then I.C.E. would have to be immediately notified and information updated to reflect them as separate categories.
As for those already in the country. They would have to immediately register with I.C.E.. They would be vetted and placed on work Visas if appropriate. If found to have criminal or terrorist affiliation they would be immediately placed on the barment list and deported. Same goes for anyone failing to register.
