Will I be considered an international or American student?

I have a Jordanian passport and American passport. If I was to go to an American university, MIT for example, would I be considered an American student?

In MIT specifically, American students have a two year highschool foreign language requirement. If I am considered a national student, would Arabic fulfill this requirement. I’ve been studying Arabic and English since first grade, so Arabic isn’t a second language, would I therefore need a world language like French for example?

If you are a US citizen (and in almost all cases, green card holder), you will be considered an American student. You then need to parse through the foreign language requirements for a particular school as a regular domestic student.

If you are a US citizen AND you live in the US, you are a straight domestic applicant.

If you are a US citizen and you live abroad, you should read the admission information for both domestic and international applicants because bits and pieces of each may apply to you. For example:

  • Modified academic entrance requirements for students educated in a non-American setting (e.g. the University of Michigan's admission requirements by country: https://admissions.umich.edu/apply/international-students/requirements-deadlines/requirements-country)
  • English proficiency requirement: colleges may ask for TOEFL scores to document your English skills
  • International supplement to the secondary school report if you attended a non-American high school
  • If you are looking at public universities, be prepared that there may be no state in which you qualify for in-state tuition or scholarships.

To answer this question specifically, MIT does not appear to have a foreign language requirement for admission, just a “recommendation.”

We recommend (please note that these are not “requirements”) that your high school years include the following: … Two years of a foreign language

I have never personally encountered a university that did not count the study of a second language towards the “foreign language requirement” for admission because an applicant happened to be bilingual.
