Am I International?

Some schools only require English proficiency test if HS language of instruction is not in English.

For example, UCSC:

We require all applicants who attend a school in a country where English is not the native language or whose language of instruction in high school (secondary school) was not English to adequately demonstrate English competency as a part of the application process. In most cases, if less than three years of your secondary schooling was with English as the language of instruction, you must meet UCSC’s English proficiency requirement.

Some schools require English proficiency test if English is not native language.

For example, USC:

All international applicants whose native language is not English must demonstrate English proficiency in the following manner:

First-year applicants must submit TOEFL, SAT, or ACT scores
Transfer applicants must submit TOEFL score
Freshman and transfer applicants whose native language is English are presumed to be proficient. This includes applicants from countries such as the United Kingdom, Australia, New Zealand, and Canada (except Quebec) where English is both the first language of the country and the language of instruction.
