What You Can & Can't Do on an F-4 Visa

The F-4 visa is prized for its flexibility — but it isn't unlimited. Knowing exactly what you can and can't do keeps you compliant.

Unsure if your job is allowed? Ask a consultant.

What you CAN do

Most professional, office, technical, and skilled work — without a separate work permit.
Run a business.
Study.
Live long-term in Korea and move toward F-5 permanent residency.

What you CAN'T do

Certain simple-labor / unskilled occupations are restricted on the F-4.

This is the single most common F-4 misunderstanding. If your intended role might be unskilled/simple-labor, check the current rules first — the line matters.

Staying compliant

Confirm your job type isn't restricted.
Keep address registration and renewals current.
Re-check rules when your work situation changes.

Why it still beats most work visas

Even with the restriction, the F-4's freedom — no single-employer tie, business allowed, study allowed — makes it far more flexible than an E-series work visa.
