Understanding what Form I-20 is the essential first step toward preparing a successful US student visa application.

What is Form I-20 and Who Needs It?

Technically, **what is Form I-20**? The I-20 form is formally known as the **”Certificate of Eligibility for Nonimmigrant Student Status.”** It is an official document issued by a US university, college, or academic institution certified by the Student and Exchange Visitor Program (SEVP) to prospective international students.

Simply put, the I-20 serves as proof that:

  • You have been accepted by a certified US school into a full-time academic program.
  • You have demonstrated sufficient financial resources to cover at least your first year of study. This answers a crucial part of the question: **What is Form I-20**? It is a dual confirmation of both academic and financial readiness.

Essentially, any international student seeking an **F-1 visa** (for academic study) or M-1 visa (for vocational study) is required to have a valid **Form I-20**.

Breaking Down the Structure of the US Study I-20 Form

It is critically important to understand the information on your I-20, as it directly relates to filling out the DS-160 application and responding during your visa interview. Here is a section-by-section guide on how to check your **US study I-20 form**:

1. Student’s Personal Information

This is the first and most vital section. Double-check every character:

  • **Name:** Must match the name on your passport exactly, 100%.
  • **Date of Birth and Country of Birth/Citizenship:** Ensure there are no errors.
  • **SEVIS ID:** This is your unique identifying number in the **SEVIS** system. This number starts with an “N” and is inseparable from the concept of **what Form I-20 is**. You will use it to pay the SEVIS I-901 fee.

*Expert Advice: Even the smallest mistake in this section can cause major problems. If you find an error, immediately contact the school’s **DSO** (Designated School Official) to request a corrected I-20.*

2. School Information

This section provides information about where you will be studying, including the school name, address, and School Code. You will need this information when completing the DS-160 form.

3. Program of Study Information

This section details your academic plan:

  • **Education Level:** Bachelor’s, Master’s, PhD, etc.
  • **Major:** Must be accurate according to the program you enrolled in.
  • **Program Start/End Date:** The start date is the important milestone for when you must arrive in the US. The end date is the maximum time allowed to complete your program legally.

4. Financial Information

This is the section the Consulate scrutinizes closely. To fully appreciate **what Form I-20 is**, you must pay attention here. It includes two main columns:

  • **Estimated Costs:** Includes tuition, living expenses, insurance, and other costs for one academic year.
  • **Funding Sources:** Shows how you will cover these costs (personal/family funds, scholarship from the school, other sources).

*Expert Advice: The total amount in the “Funding Sources” column must be equal to or greater than the total in the “Estimated Costs” column. This is the financial proof accepted by the school.*

The 4-Step Process to Apply for the US Study I-20

To understand **what Form I-20 is** in practical terms, you need to master the following 4-step process:

  1. **Step 1: Receive the Official Acceptance Letter:** After your application is approved, the school will send a congratulatory letter and outline the next steps.
  2. **Step 2: Submit Financial Documentation to the School:** You must provide documents like bank statements and balance confirmation letters to prove you can cover at least the first year’s costs.
  3. **Step 3: Complete Other Formalities and Pay Fees:** Some schools may require you to pay an enrollment deposit to hold your place before the I-20 is issued.
  4. **Step 4: The School Issues and Sends the I-20 to You:** After verifying all information, the school’s DSO will create the **Form I-20** in the SEVIS system and mail the physical copy to you.

Understanding the I-20’s “Make-or-Break” Role in the Visa Application

The I-20 is not just a piece of paper; it is the foundational document for your entire **US student visa application**.

  • **For Paying the SEVIS I-901 Fee:** You must have the SEVIS ID from your I-20 to pay this mandatory fee. The SEVIS fee receipt is a required document for your interview.
  • **For Completing the DS-160 Form:** A significant amount of information on the non-immigrant visa application (DS-160) is taken directly from the I-20.
  • **The Central Document During the Interview:** The Consular Officer will hold your I-20 and ask questions based on it. All your answers must demonstrate that you understand **what Form I-20 is** and your academic plan clearly.

Key Considerations When Handling Your I-20

  • **Sign Your I-20:** Immediately upon receipt, check the information and sign the “Student Attestation” section.
  • **Always Carry It for US Entry/Exit:** You must present your I-20 along with your visa and passport to the Customs and Border Protection officer.
  • **I-20 Extension:** If you cannot complete your program by the end date listed on the I-20, you must contact your DSO to apply for an extension.
  • **I-20 Updates:** Any change to your major, academic level, or funding sources requires an update to your I-20. Understanding **what Form I-20 is** also involves knowing your responsibility to keep your information current.
