How do college admissions look at online ap courses

my school doesnt allow me to take AP ENG and AP USH because i am an international student and i came to shool during soph yr. i am wondering if i take these courses online, how will college admissions feel? will they be treated equally with ap courses in school? what if i tell them that i cant take them in school because of conflicting schedules? what if i take ap courses online which are not provided in school? thanks so much~
