International applicants to Petrozavodsk State University (PetrSU) for undergraduate admission typically need a passport (translated into Russian), a previous high school diploma or certificate with transcripts (notarized or translated), proof of English or Russian proficiency (depending on program), and occasionally a medical certificate. Program-specific requirements vary, such as MBBS requiring NEET for Indians. Document submission, possible interviews, and assistance with obtaining a visa from the university's foreign office are all part of the application process.
