Before you can begin the process of acquiring a visa, you will need a Certificate of Eligibility (COE). A Certificate of Eligibility for Nonimmigrant Student Status, is a document issued by a U.S. educational institution certified by the Student and Exchange Visitor Program (SEVP) or the Department of State (DOS) to international students accepted into a full-time academic or language program. It serves as proof of acceptance and demonstrates that the student has the financial resources to cover their educational and living expenses while studying in the U.S
You can join a university as a student in F-1 status using an I-20 or in J-1 status using a DS-2019. You will also need a this document for other important steps in the arrival process.
