“Condiciones” covers “nationality,” “race,” “ethnicity,” and “socioeconomic status” (just as “background” is intended to do in English).

Real-world translation:
“Don’t worry if you goofed off in high school and got lousy grades. We aren’t too picky in our admission criteria. Especially since, as an “international student” you and your family will be paying full out-of-state tuition to attend our university.”
