If the schools are down on enrollment, then it's money in their coffers. If the students are paying out of their pocket (family's pocket)...win/win. (Assuming work permit, etc.) They should only be allowed to attend if they're not displacing a U.S. citizen, either in-state or out-of-state.
BUT: IN NO WAY, SHAPE OR FORM SHOULD THEY RECEIVE ONE CENT OF TAXPAYER MONEY TO FUND THEIR EDUCATION. AND THEY SHOULD NOT RECEIVE PREFERENTIAL TREATMENT IN ADMISSION BASED ON THEIR ETHNICITY. PERIOD.
Over the wintry
forest, winds howl in rage
with no leaves to blow.
