I’m a US citizen having been born in New York. And I have attended school in the US since pre-school all the way to my high school graduation. Now I am living in South Korea and want to attend university here. Does that still require me to take the TOEFL test? Do I need any type of english proficiency test?
You want to attend a university in South Korea or in the US?
Doubtful, but there is no consistent guideline across colleges as to TOEFL submission. Your best bet is to ask the college in question.
