F-1 Student Visa

What it permits

The F-1 visa is the standard US student visa for academic study at universities, colleges, conservatories, seminaries, and academic high schools. It permits the holder to:

• Live in the US legally as a full-time student
• Work on-campus up to 20 hours/week during the academic semester
• Work on-campus full-time during summer and winter breaks
• Apply for OPT (Optional Practical Training) — up to 12 months of post-graduation work authorization in the US, with a 24-month extension for STEM degrees
• Apply for CPT (Curricular Practical Training) — internships during studies if required by your degree program
• Travel in and out of the US during the visa's validity (with valid I-20 endorsement)

The F-1 visa is "non-immigrant" — meaning when you apply, you sign a declaration that you intend to return to your home country after completing your studies. This is enforced at the embassy interview, where the consular officer assesses whether you have demonstrated "non-immigrant intent."

The application process

For Korean students, the F-1 visa application has these steps in order:

1. Receive I-20 from your US college (after admission + Certification of Finances approval)
2. Pay the SEVIS fee ($350 USD) online at fmjfee.com
3. Complete the DS-160 visa application form online — this is the actual visa application, separate from the school application
4. Pay the visa application fee ($185 USD)
5. Schedule an interview at the US Embassy in Seoul (or a US Consulate) — book early because slots fill up in summer
6. Attend the interview with all required documents in hand
7. Wait for processing — usually 1–7 days; passport with visa is returned by courier or pickup

What to bring to the interview

• Valid passport (must be valid for at least 6 months beyond your intended stay)
• I-20 form from your US school
• SEVIS fee receipt
• DS-160 confirmation page with barcode
• Visa application fee receipt
• Passport photo (2 inches × 2 inches, white background)
• Financial documents proving ability to pay (bank statements, sponsor letters)
• Acceptance letter from the US college
• Academic records (transcripts, test scores) — sometimes asked
• Optionally: any documents proving ties to Korea (family, property, future plans)

What the consular officer is evaluating

The interview itself is short — usually 2–5 minutes. The consular officer is making one core determination: are you a legitimate student who intends to return to Korea after graduation?

They evaluate this through:

• Financial sufficiency: do you have the money to actually attend? (CoF documentation matters here)
• Academic credibility: does your story make sense? Why this school, why this major, why now?
• Non-immigrant intent: do you have demonstrable ties to Korea (family, future career plans, mandatory military service for Korean men)?

For most Korean students with strong applications and clear plans, the F-1 visa interview is straightforward and the visa is approved on the spot. Refusals do happen — most often when the student gives vague or inconsistent answers about why they're going to a particular school, or when financial documents look insufficient.

Common Korean student concerns

Mandatory military service: Korean male students who haven't completed military service can study in the US on an F-1 visa, but must return to fulfill their service obligation eventually. Many use a deferral (병역 연기) granted for full-time university study. This is a normal accommodation — both the Korean government and US consular officers understand it.

Visa renewal: F-1 visas have an expiration date separate from the I-20 program length. If your visa expires while you're still studying in the US, you can stay in the US legally on the still-valid I-20, but you must renew the visa at a US embassy outside the US (typically in Korea over a summer break) before any US re-entry.

OPT and STEM extension: after graduation, F-1 students can apply for 12 months of work authorization (OPT) to work in the US in a field related to their degree. Students with STEM degrees (computer science, engineering, math, physics, biology, etc.) can extend OPT by an additional 24 months — totaling 36 months of post-graduation work authorization. This is one of the strongest reasons US STEM programs attract international students: the post-graduation work pathway is real.
