United States Student Visa
Strategic Navigation of the I-20, SEVIS, and Consular Interview.
The Five-Stage F1 Protocol
Institution Certification (I-20)
Your journey begins only after receiving the **Form I-20** from a SEVP-certified institution. This document is your digital identity in the US immigration system and contains your unique **SEVIS ID**.
SEVIS I-901 Infrastructure Fee
Mandatory payment of **$350** is required to activate your record in the Student and Exchange Visitor Information System. This must be completed at least 3 days before your interview.
Consular Visa Application (DS-160)
The **DS-160** is the most critical piece of written evidence. It tracks your background, family ties, and "Non-immigrant Intent." Errors here are the leading cause of administrative processing delays.
Consular Logic: The 214(b) Filter
Under US law, every applicant is presumed to be an "intending immigrant" until they prove otherwise. To succeed, you must demonstrate **Strong Ties** to your home country, such as family property, job offers, or specialized career paths that only exist in your region.
