English: Required if your bachelor’s degree comes from a country where English isn’t the sole official language, whatever your citizenship. The minimums are TOEFL 100 (5.5 on the new scale), IELTS 7.5, or Duolingo 135.
Waivers: You can request a waiver if your bachelor’s was taught entirely in English, or if you hold a master’s or PhD from a country where English is the sole official language. Send the request at least two weeks before your deadline.
Degrees: Three-year bachelor’s degrees are accepted from several countries, including India, Pakistan, and Australia, and from any Bologna Process country.
Scores: Official scores must arrive within two weeks of your program’s deadline, and scores more than two years old aren’t accepted.
Visas: If you’re admitted and need a student visa, you apply to Columbia’s International Students and Scholars Office for an I-20 or DS-2019, showing funding for your first year’s tuition, fees, and living costs.
The Economics MA: Take the TOEFL or IELTS unless you spent at least two years of your bachelor’s at an English-speaking university in an English-speaking country. The department accepts no other test, even though GSAS’s page for the program also lists Duolingo. It’s STEM-designated, so F-1 students can apply for extra work permission after graduating (STEM OPT).
