F-1 International Student Visa: Status, Work, and Travel Rules

The F-1 student visa is the nonimmigrant category for full-time academic study in the United States, and its rules and requirements cover four things: where you can study, how you enter, what you must do to stay in status, and when you’re allowed to work. It’s issued for enrollment at colleges, universities, seminaries, conservatories, academic high schools, elementary schools, and language programs at schools the federal government has certified to accept foreign students.¹ It’s academic only. Vocational and technical programs fall under the separate M-1 classification.

Who Qualifies

Federal regulations at 8 CFR 214.2(f) draw a hard line between academic and vocational study. Your school must be certified by the Student and Exchange Visitor Program (SEVP), the only entity authorized to approve schools for enrolling international students.² The program must lead to a degree, diploma, or certificate.

Before a consular officer approves the visa, you also have to show enough English proficiency to handle the coursework (or be enrolled in courses that will get you there), and you have to convince the officer you intend to return to your home country after finishing. That last piece is the foreign residence requirement. Evidence of ties back home, whether family, property, or a job offer, is what carries it.

Documents and Fees

The paperwork chain begins with Form I-20, the Certificate of Eligibility for Nonimmigrant Student Status. A Designated School Official (DSO) at your SEVP-certified school issues it through the Student and Exchange Visitor Information System (SEVIS) after you’ve been admitted and shown you can pay.³ You’ll give your school a copy of your passport and financial documentation covering tuition and living costs.

Financial proof is where applications get tricky. Bank statements showing sufficient funds are the most common evidence, but scholarship award letters and signed affidavits from financial sponsors also work. A sponsor typically has to provide their own bank statements and a letter committing to support you.

With the I-20 in hand, pay the I-901 SEVIS fee of $350 through the official ICE portal and save the receipt for your interview.⁴ Then complete Form DS-160, the Online Nonimmigrant Visa Application, through the Department of State’s Consular Electronic Application Center.⁵ It asks for personal history, educational background, and your intended U.S. address. At the end you get a barcode confirmation page to bring to the interview. The non-refundable visa application fee is $185.⁶

The Interview and Admission

At the U.S. Embassy or Consulate, a consular officer decides whether you’re a genuine student with the means to study and a real intention to go home afterward. Questions typically focus on why you chose your specific school and program, how you’ll pay, and what you plan to do after graduation. Clear, specific answers matter more than rehearsed speeches. If approved, your passport is held for a few days while the visa stamp is affixed.

When you land, Customs and Border Protection (CBP) creates an electronic I-94 arrival/departure record showing you were legally admitted and how long you can stay. You can access it at i94.cbp.dhs.gov or through the CBP One mobile app. As of late 2025, the I-94 fee is $30.⁷

F-1 students are admitted for “duration of status,” marked “D/S” on the I-94. Your authorized stay lasts as long as you maintain valid F-1 status, not a fixed calendar date. The visa stamp itself can expire while you’re still lawfully present, because it’s only an entry document. Your I-20 and active SEVIS record are what keep you in status once you’re here.

Staying in Lawful F-1 Status

This is where most students run into problems, often without realizing it until the damage is done.

Full Course of Study

You must be enrolled full-time during every required academic term. The school defines the credit threshold. One detail that catches students off guard: no more than one online class (or three credits) per term can count toward the full-time requirement. The rest must involve physical attendance.⁸ If you drop below full-time without your DSO’s approval first, you’re immediately out of status. No grace period, no automatic fix.

Authorized Reduced Course Loads

Your DSO can authorize a lighter course load, but only for specific reasons:⁹

A documented medical condition, verified by a licensed physician or psychologist, limited to a total of 12 months per program level. This can excuse you from all classes if necessary.
Academic difficulty during your first academic term only, such as unfamiliarity with U.S. teaching methods or initial struggles with English. You must still carry at least six credit hours.
A final semester in which you need fewer than a full load to finish your degree, as long as you’re enrolled in at least one required course.

Reporting Obligations

Report any change of address to your DSO within 10 days of moving.¹⁰ Report changes to your major or program of study promptly so your I-20 stays accurate. Your DSO updates SEVIS, but flagging the change is on you. Keep your passport valid with at least six months of remaining validity at all times.¹¹

The 60-Day Grace Period

After completing your program and any authorized practical training, you have 60 days to leave the country, transfer to another school, or change to a different immigration status.¹² You cannot work during this period.

Working on an F-1 Visa

Employment options exist but are tightly controlled. The fastest way to lose F-1 status is working without authorization.

On-Campus Employment

You can work on campus for up to 20 hours per week while school is in session, and full-time during breaks and summer vacation.¹³ On-campus jobs don’t require a separate work permit, but you do need DSO approval.¹⁴

Curricular Practical Training

Curricular Practical Training (CPT) lets you work off campus in a position directly related to your major, but only when the work is a required or integral part of your curriculum. Your DSO authorizes CPT and notes it on your I-20. If you use 12 months or more of full-time CPT, you lose eligibility for post-completion Optional Practical Training.¹⁵

Optional Practical Training

Optional Practical Training (OPT) provides up to 12 months of work authorization in a job related to your field of study. Your DSO recommends the OPT in SEVIS, and you file Form I-765 with USCIS.¹⁶ You must file within 30 days of the DSO’s recommendation.¹⁷ If approved, USCIS issues an Employment Authorization Document (EAD).

Students with degrees in science, technology, engineering, or mathematics can apply for a 24-month STEM OPT extension on top of the initial 12 months, for a potential total of 36 months.¹⁸ The extension requires a formal training plan developed with your employer.

Severe Economic Hardship

After at least one full academic year in F-1 status, unexpected financial problems beyond your control may qualify you for off-campus work authorization. Qualifying circumstances include loss of financial aid or on-campus employment through no fault of your own, major currency fluctuations, unexpected tuition increases, or substantial unforeseen expenses like medical bills.¹⁴ Your DSO recommends you on a new I-20, and you file Form I-765. If approved, the EAD is granted in one-year increments.

Social Security Number

You cannot apply for a Social Security Number without an authorized employment offer. Once you have a qualifying job, bring your employment documentation along with your passport, I-20, and I-94 to a local Social Security Administration office. You’ll need the SSN to get paid and to file taxes.

Travel and Re-Entry

When you return from abroad, CBP officers will want to see your valid passport (with at least six months of remaining validity), a valid F-1 visa stamp, your most recent I-20 with a current travel signature from your DSO, and your I-901 SEVIS fee receipt.¹¹ Carry recent transcripts and proof of enrollment for the upcoming term as well.

The travel signature is what students most often forget. For enrolled students, a DSO’s travel signature is valid for one year. For students on OPT, it’s valid for six months. Get a fresh signature before every international trip if yours is close to expiring.

One useful rule: if your visa stamp has expired but your I-94 and status are still valid, you can re-enter after a trip of 30 days or fewer to Canada, Mexico, or certain adjacent islands under automatic visa revalidation.¹⁹ Travel to Cuba disqualifies F-1 students from automatic revalidation.

Transferring Schools

If you switch institutions, you don’t need a new visa or a new SEVIS ID number. The transfer moves your existing SEVIS record electronically from your current school to the new one.²⁰ Your current school’s DSO cannot refuse to transfer your record just because you want to leave.

You must maintain full-time enrollment at your current school until the transfer release date. Once the transfer-in school receives your record, contact the new DSO within 15 days of the program start date and register for classes. The new school must set your SEVIS record to active status within 30 days of the program start. If you don’t show up or don’t enroll full-time, the new school is required to terminate your record.²⁰

Family on F-2 Dependent Visas

Your spouse and unmarried children under 21 can accompany you on F-2 dependent visas. The restrictions are significant. F-2 dependents cannot work in the United States at all. Children can attend elementary, middle, and high school full-time, and adult dependents can take recreational or part-time classes. If your spouse or older child wants to pursue a full-time college or university program, they need their own F-1 status through a change of status application.²¹

Federal Tax Obligations

Every F-1 student physically present in the United States has a federal tax filing obligation, even those who earned nothing all year. If you had no U.S.-source income, you still file Form 8843, an informational statement the IRS uses to track your days of presence for tax residency purposes.²² You don’t need an SSN or Individual Taxpayer Identification Number to file Form 8843 if it’s the only form you’re submitting.

If you earned wages, received a taxable scholarship, or had other U.S.-source income, file Form 1040-NR in addition to Form 8843. Common supporting documents include Form W-2 for wages and Form 1042-S for scholarship income. Income exempt under a tax treaty still needs to be reported.

FICA Exemption

F-1 students in their first five calendar years in the United States are generally exempt from Social Security and Medicare (FICA) taxes on wages from authorized employment.²³ The exemption applies to on-campus jobs, off-campus employment authorized by USCIS, and practical training. It saves you 7.65% of your gross pay, and it saves your employer the matching 7.65%.

The exemption disappears once you become a resident alien for tax purposes, which typically happens after five calendar years under the substantial presence test. It also doesn’t apply to F-2 dependents or to employment that isn’t authorized under your visa status.²³ If your employer withholds FICA in error during your exempt period, you can file for a refund.

If You Fall Out of Status

Common triggers include dropping below full-time enrollment without DSO approval, working without authorization, failing to report an address change, or letting your I-20 expire. Once your SEVIS record is terminated, you’re considered out of status and technically need to leave the country immediately.

Reinstatement is possible but far from guaranteed. You file Form I-539 with a new I-20 showing your DSO recommends reinstatement. USCIS will consider the request only if you meet all of these conditions:²⁴

You filed no more than five months after falling out of status, or you can show exceptional circumstances for the delay.
You don’t have a history of repeated or willful immigration violations.
You are currently pursuing or intend to immediately pursue a full course of study.
You have not engaged in unauthorized employment.
The violation resulted from circumstances beyond your control, or it involved a course load reduction your DSO could have authorized and denying reinstatement would cause extreme hardship.

Reinstatement is discretionary. USCIS can deny it even if you technically meet every criterion, and criminal violations or deliberate actions that caused the status loss weigh heavily against approval.²⁴ If denied, you may need to leave and apply for a new visa from abroad. Staying in close contact with your DSO at the first sign of trouble is the single most important thing you can do to protect your status.
