F-1 Visa: Requirements, Application, and Work Authorization

The F-1 student visa lets you enter the United States to study full-time at an accredited academic school, college, university, seminary, or language program that has been certified by the Student and Exchange Visitor Program. Getting one requires acceptance at a certified school, a Form I-20 issued in your name, proof that you can pay for the program, and a consular interview. Keeping it requires continuous full-time enrollment, careful attention to work rules, and prompt reporting of changes to your school. The consequences of missing a requirement range from processing delays to losing your legal status outright, so the details below matter.

Who Qualifies

You need acceptance into a full-time academic program at a school certified by the Student and Exchange Visitor Program (SEVP). The F-1 category covers degree programs, diploma programs, certificate programs, and English language training at SEVP-certified institutions.¹ Vocational and technical training uses a different visa (M-1); if your program is hands-on trade training rather than academic coursework, the F-1 is not the right classification.

You must also show that you have a residence abroad that you do not intend to abandon.² U.S. immigration law presumes every visa applicant plans to stay permanently, and the burden is on you to prove otherwise.³ Consular officers weigh family relationships, property, and job prospects waiting for you at home. Weak ties are one of the most common reasons F-1 applications get refused.

Financially, you need to show funds for tuition and living expenses for the whole program. For the first year, the money must be immediately available. For later years, you can rely on a credible plan such as continuing family support, scholarship renewals, or an assistantship.² Bank statements, scholarship award letters, and sponsor affidavits are the usual evidence.

English proficiency is expected, unless you are enrolling in a language training program designed to build those skills.⁴

Public School Limits

F-1 students may attend private elementary and secondary schools freely. Public schools are tightly restricted. You cannot attend a public elementary or middle school on an F-1 at all. Public high school attendance is capped at 12 months total, and you must pay the school district the full, unsubsidized per-capita cost of your education, typically between $3,000 and $10,000.⁵ The district cannot waive that payment, even if you live with a U.S. citizen relative who pays local property taxes.

Form I-20 and the SEVIS Fee

Once a school accepts you, it issues Form I-20, the Certificate of Eligibility for Nonimmigrant Student Status. The I-20 carries your SEVIS identification number, the school’s code, your program start and end dates, and the estimated cost of attendance the school verified.⁶ Every detail on it must match your passport and your visa application, so check it carefully when it arrives.

Before applying for the visa, pay the I-901 SEVIS fee, which is $350 for F-1 students.⁷ You pay it online using your SEVIS ID number and school code from the I-20.⁸ Print the receipt. You will need it at your interview.

Applying for the Visa

Complete the DS-160 Online Nonimmigrant Visa Application through the Department of State’s Consular Electronic Application Center.⁹ It asks for detailed personal, travel, and education history, and everything must line up with your passport and I-20. When you submit, save the barcode confirmation page for your interview.

Then pay the $185 nonimmigrant visa application fee.¹⁰ Payment methods vary by location. Once it clears, use the receipt to book an interview at a U.S. embassy or consulate. At popular posts, wait times can stretch to several months during peak seasons, so schedule as early as you can.

The Interview

At the appointment you go through security screening, have your fingerprints scanned, and sit down for a brief conversation with a consular officer. The officer reviews your documents and asks about your academic plans, your ties to your home country, and how you will pay for your studies. They are looking for consistency between what you say and what your paperwork shows.

The officer usually gives you the decision on the spot. If approved, the embassy keeps your passport for a few business days to attach the visa foil, then returns it by courier or at a designated pickup location. Your passport must be valid for at least six months beyond your intended stay, unless your country has an agreement allowing a shorter validity window.¹¹

Administrative Processing

Some applications get placed into administrative processing under Section 221(g) of the Immigration and Nationality Act instead of receiving an immediate decision. The officer needs more information or a background check before finalizing the case. This is not a denial.¹²

If the officer requests documents, you have one year from the refusal date to provide them. If the case just needs security clearance, the wait can run from weeks to several months, with students in certain STEM fields more often affected. There is no expedite process, so if your program start date is approaching, ask your school’s international student office about deferring enrollment.

Entering the U.S.

You may enter the country up to 30 days before the program start date on your I-20, but not earlier.¹³ At the port of entry, a Customs and Border Protection officer reviews your passport, visa, and I-20 and stamps you in. F-1 students are admitted for “duration of status,” often written as “D/S” on the I-94. You can stay as long as you are progressing toward completing your program plus any authorized practical training.

Duration of status cuts both ways. You do not need to renew anything each time your visa foil expires; the foil only controls entry, not how long you can stay. But the moment you stop meeting the conditions of your status, say by dropping below full-time or working without authorization, your lawful presence ends immediately, even if the sticker in your passport still looks valid.

Staying in Status

Staying in valid F-1 status takes active effort throughout your program. The core rule is a full course of study every mandatory academic term. Undergraduates at a college or university need at least 12 credit hours per term. Graduate students take whatever the school certifies as a full load.⁴ Language training students meet either 18 clock hours per week (mostly classroom) or 22 clock hours per week (mostly lab or field work).

Dropping below full-time without permission from your Designated School Official (DSO) puts you out of status immediately. A DSO can authorize a reduced course load in only three situations:¹⁴

Academic difficulty, allowed once per program level, and you still need at least six credit hours and must resume a full load the next term.
A medical condition documented by a licensed medical professional. This can be authorized more than once, but the total cannot exceed 12 months at any given program level.
The final semester, when you need fewer courses than a full load to finish the degree.

You also have to report any change of address to your school within 10 days of moving so it can be updated in SEVIS.¹⁵ This is a federal requirement, not a school preference.¹⁶

Working Legally

Working without authorization is one of the fastest ways to lose F-1 status, and it makes recovery difficult. The rules create a narrow set of options that widen as you move through your program.

On Campus

From your first day, you can work on campus up to 20 hours per week while school is in session, and full-time during breaks and vacations.¹⁷ On-campus employment covers jobs at the school itself or at a commercial business on school premises that serves students, like a campus bookstore or cafeteria. You need approval from your DSO but not a separate government work permit. Exceeding the hour limit counts as unauthorized employment.¹⁸

Curricular Practical Training

Curricular Practical Training (CPT) is off-campus work that is an integral part of your curriculum, such as a required internship or cooperative education placement. You generally need one full academic year of enrollment before you’re eligible. Graduate students whose programs require immediate practical experience can get an exception.¹⁹ The DSO authorizes CPT directly by updating your I-20, and the work must relate to your field of study. Watch this trap: if you use 12 or more months of full-time CPT, you lose eligibility for Optional Practical Training after graduation.

Optional Practical Training

Optional Practical Training (OPT) is the benefit most students plan around. After completing one full academic year, you become eligible for up to 12 months of work authorization in a position directly related to your major.²⁰ Most students use OPT after they finish their degree, though some of it can be used during the program.

Your DSO recommends OPT in SEVIS and issues an updated I-20 before you file Form I-765 with USCIS. You must file within 30 days of that recommendation. Filing too early or too late results in a denial, and you lose the application fee.²¹ You cannot start working until USCIS issues your Employment Authorization Document, which often takes several months.

While on post-completion OPT, you are limited to 90 cumulative days of unemployment. Every day you are not working counts, and gaps between jobs add up fast.²² Going over is a status violation.

STEM OPT Extension

If your degree is on the DHS STEM Designated Degree Program List, you can apply for an additional 24 months of work authorization on top of the standard 12-month OPT. The requirements are stricter:²³

You must currently be in valid post-completion OPT and file before it expires.
The qualifying bachelor’s, master’s, or doctoral degree must be from an SEVP-certified school accredited by a recognized agency.
Your employer must be enrolled and in good standing with E-Verify.
You and your employer must complete Form I-983, a formal training plan showing how the position builds on your academic knowledge.
The job must be paid, with compensation comparable to what a similarly situated U.S. worker would earn.

During the STEM extension, the unemployment cap rises to 150 total days across the entire OPT period, including days accumulated in the initial 12 months.²² Your employer also has to report any material change to the training plan or your termination to the DSO within five business days.

Traveling and Returning

Leaving the country during your studies is common, but re-entry needs preparation. You need three things: a valid passport, a valid visa foil (unless you qualify for automatic revalidation), and an I-20 signed for travel by your DSO within the past year. On OPT, that travel signature is only valid for six months.

If your visa foil has expired but you’re only visiting Canada, Mexico, or certain adjacent Caribbean islands (Cuba excluded) for fewer than 30 days, you can re-enter without a new visa under automatic visa revalidation. You need a valid I-94 record, a valid passport, and your endorsed I-20, and you cannot have applied for a new visa while abroad.²⁴ Citizens of countries designated as state sponsors of terrorism do not qualify.

Travel beyond those countries with an expired foil means you’ll need a new visa at a U.S. embassy before you can come back. Build in extra time; consular appointments are not guaranteed quickly, and administrative processing can add weeks.

Family Members on F-2 Visas

Your spouse and unmarried children under 21 can join you on F-2 dependent visas. Each dependent needs their own Form I-20, issued by your school in their name.²⁵ Dependents must also show that you have been admitted and are enrolled in a full course of study (or will be within 30 days), or that you are on authorized practical training.

F-2 restrictions are significant. Dependents cannot work in the United States at all. Children may attend elementary through high school full-time, and any dependent can take part-time or recreational courses, but a dependent who wants to enroll full-time in postsecondary study must change status to F-1 by filing their own application. F-2 status is tied to yours: it lasts as long as you maintain F-1.

Taxes

Every F-1 student in the United States must file Form 8843 with the IRS each year, even if you had no income. The form excludes your days of presence from the substantial presence test that would otherwise make you a tax resident.²⁶ With no U.S. income, mail the form on its own. With income, attach it to your tax return.

Unlike U.S. citizens, nonresident aliens have no minimum income threshold for filing. Any taxable income (wages, scholarship amounts beyond tuition, or treaty-covered income) means you file Form 1040-NR.²⁷ The taxable portion of a scholarship (anything over tuition and required fees) counts as income you have to report.

During your first five calendar years in the country, you are generally exempt from Social Security and Medicare taxes on wages from employment authorized under your visa, including on-campus jobs, CPT, and OPT.²⁸ If an employer withholds FICA anyway during that period, you can request a refund. After five years, you may become a resident alien for tax purposes and the exemption ends.

The 60-Day Grace Period

After you finish your degree and any authorized practical training, you get 60 days to prepare to depart, transfer to another school, or change to a different immigration status.²⁰ You cannot work during this window. The 60 days run from your program end date if you did not use OPT, or from the end of your OPT if you did.²⁹

If your DSO authorizes you to withdraw from classes instead, the departure window shrinks to 15 days. And if you fall out of status without DSO approval, by dropping below full-time on your own for example, you get no grace period at all.²⁰

Reinstatement If You Fall Out of Status

Reinstatement is possible but not guaranteed. You file Form I-539 with USCIS and must meet all of the following:²⁰

You filed within five months of falling out of status, or you can show exceptional circumstances prevented earlier filing.
You do not have a pattern of repeated or willful violations of immigration rules.
You are currently pursuing, or about to pursue, a full course of study at the school that issued your I-20.
You have not engaged in unauthorized employment.
You are not otherwise deportable, meaning the status violation is your only ground for removal.
The violation was beyond your control, such as serious illness, school closure, natural disaster, or a DSO error. Alternatively, you can show that the violation involved a course load reduction the DSO could have authorized and that denial would cause extreme hardship.

Reinstatement is discretionary. USCIS can deny it even when all conditions are met. The unauthorized employment bar trips up the most students; even a single shift at an off-campus job without authorization essentially closes the door. If reinstatement isn’t viable, the remaining options are usually leaving the country and applying for a new visa from abroad, or changing to another immigration status if you qualify.
