### User's Query:
What is the name of the university that had the highest number of international students for 6 consecutive years?

### Extra Knowledge:
had the highest number of international students refers to max(pct_international_students); for 6 consecutive years refers to count(SUBTRACT(year, rm)) > = 6; name of university refers to university_name;
SELECT T2.university_name FROM university_year AS T1 INNER JOIN university AS T2 ON T1.university_id = T2.id ORDER BY T1.pct_international_students DESC LIMIT 1
