The F-1 visa is the U.S. nonimmigrant classification for foreign nationals who want to study full-time at an American school, from elementary grades through doctoral research and language training. To get one, you need admission to a school certified by the Student and Exchange Visitor Program (SEVP), proof you can pay for your education, and evidence you plan to return home when your program ends. Once you arrive, keeping the visa valid depends on how many classes you take, where you work, and whether you report changes to your school on time.
Who Can Qualify
You need three things: acceptance from an SEVP-certified school, enough money to cover tuition and living expenses without unauthorized work, and a residence abroad you have no intention of abandoning. The federal statute defining F-1 eligibility bakes that last requirement directly into the law.1Office of the Law Revision Counsel. 8 USC Chapter 12 – Immigration and Nationality Consular officers look for family relationships, property, or a job waiting at home as signs you will leave when studies end.
Eligible schools include accredited colleges, universities, seminaries, conservatories, private K–12 schools, and intensive language training programs. You can verify a school’s current SEVP certification through the School Search tool on the Department of Homeland Security’s Study in the States website.
A boundary worth flagging early: F-1 rules for public schools at the K–12 level are strict. You cannot attend a U.S. public school below ninth grade on an F-1 visa at all. Public high schools are capped at 12 months total across all such schools, and you must reimburse the full, unsubsidized per-student cost before applying. Private K–12 schools have no such time limit.2Study in the States. F-1 Kindergarten through Grade 12
What It Costs Before You Even Start Classes
Government fees stack up before tuition. The SEVIS I-901 fee for F-1 students is $350, paid online at FMJfee.com after your school issues Form I-20.3U.S. Immigration and Customs Enforcement. I-901 SEVIS Fee Frequently Asked Questions The nonimmigrant visa application fee (the MRV fee) is $185 and must be paid before your consular interview.4U.S. Department of State. Fees for Visa Services Neither is refundable if the visa is denied.
If you later apply for work authorization through Optional Practical Training, the Form I-765 filing fee with USCIS is $410 when filed online. Most universities also require international students to carry health insurance even though no federal law mandates it, and school-sponsored plans typically run from several hundred to a few thousand dollars per year. You may not be allowed to register for classes without coverage.
How To Apply
The sequence has a specific order, and skipping steps causes delays.
Step 1: Get Your Form I-20
Before applying for the visa itself, you need Form I-20 (Certificate of Eligibility for Nonimmigrant Student Status) from your school. A Designated School Official (DSO) issues it after confirming your academic qualifications and financial resources. The I-20 lists your personal information, program start and end dates, and estimated costs. Check every detail before you leave the DSO’s office. Errors on the I-20 can derail your visa or cause problems at the port of entry.
Step 2: Pay the SEVIS Fee
Pay the $350 SEVIS I-901 fee at FMJfee.com and print the receipt. You will need it for your interview.5Department of Homeland Security. Paying the I-901 SEVIS Fee
Step 3: File the DS-160 and Schedule Your Interview
Submit Form DS-160 (the Online Nonimmigrant Visa Application) through the State Department’s website. It generates a barcode confirmation the consulate uses to pull up your file.6U.S. Department of State. DS-160 Frequently Asked Questions Then schedule an interview at the nearest U.S. Embassy or Consulate.
Step 4: The Interview
The consular officer will ask about your academic plans, how you intend to pay for school, and what you plan to do after graduating. Bring certified bank statements, scholarship award letters, or notarized affidavits of support from a sponsor. The officer wants a consistent, believable story and reasons to believe you will return home. Most decisions are made on the spot. If approved, the consulate collects your passport to place a machine-readable visa sticker inside, usually returning it within a few days. Some cases go into additional administrative processing that can add weeks.
Entering the U.S. and How Long You Can Stay
Your visa sticker lets you travel to a U.S. port of entry and request admission from Customs and Border Protection. You cannot arrive more than 30 days before the program start date on your I-20.7U.S. Department of State. Student Visa
Here is the point most students get wrong: the visa sticker in your passport is an entry document. Its expiration date only matters on days you cross the border. When CBP admits you, they mark your record “D/S,” meaning Duration of Status. You can stay in the United States as long as you are actively maintaining F-1 status, even if the visa sticker expires while you are here. A valid stamp is only needed when you leave and want to re-enter.
Re-Entering With an Expired Visa Stamp
If your sticker has expired but you take a short trip to Canada, Mexico, or certain nearby islands, automatic visa revalidation may let you re-enter without a new visa. The trip must last 30 days or less, you must have a valid I-94, a valid I-20 with a recent travel signature, and no pending visa application at a foreign consulate. Automatic revalidation does not apply if you traveled to Cuba or hold citizenship in a country on the State Department’s restricted list.8U.S. Department of State. Automatic Revalidation
Keeping Your F-1 Status Valid
Attending classes is only part of it. Several ongoing obligations run for the entire program, and letting any of them slip can end your legal stay quickly.
Full Course Load Every Term
You must carry a full course load each semester, defined by your school’s registrar. Twelve credit hours for undergraduates and nine for graduate students are typical. Dropping below without prior authorization is a status violation.
A DSO can approve a reduced course load in narrow situations: a documented medical condition, initial academic difficulty during your first term, or your final semester when you need fewer courses to graduate.9Study in the States. Reduced Course Load The medical exception is capped at 12 months per degree level. The academic difficulty exception can only be used once, and you must still carry at least half a full load. Get the DSO’s approval before dropping classes, not after.
Report Address Changes Within 10 Days
Any time you move, report your new physical address to your DSO within 10 days. The DSO then updates SEVIS within 21 days. The address on file must be where you actually live.10eCFR. 8 CFR 214.2 – Special Requirements for Admission, Extension, and Maintenance of Status
Travel Signatures on Your I-20
If you leave the country and plan to return, your I-20 needs a recent travel endorsement signature from your DSO. Without it, you may be turned away at the border even if your visa sticker is still valid.
Work Rules
Working without authorization is one of the fastest ways to lose F-1 status. The rules allow a narrow set of options, each with its own conditions.
On-Campus Work
You can work on campus up to 20 hours per week while school is in session and full-time during official breaks or summer vacation. No special application is required beyond your DSO’s awareness, but the 20-hour weekly limit during the term is strict.11ICE. Employment
Curricular Practical Training
Curricular Practical Training (CPT) covers work built into your academic program, such as a required internship or a cooperative education placement. Your DSO authorizes it by updating your SEVIS record and endorsing your I-20. The job must be directly related to your major. One catch: accumulating 12 months or more of full-time CPT makes you ineligible for post-completion OPT.10eCFR. 8 CFR 214.2 – Special Requirements for Admission, Extension, and Maintenance of Status
Optional Practical Training
Optional Practical Training (OPT) gives you up to 12 months of work authorization tied to your field of study. You can use it before graduation (pre-completion OPT, capped at 20 hours per week during the school year) or after (post-completion OPT, at least 20 hours per week). Each higher degree level unlocks a fresh 12 months.12ICE. Practical Training
The DSO enters a recommendation in SEVIS and issues an updated I-20, and then you file Form I-765 with USCIS. You cannot start working until you receive your Employment Authorization Document card.13U.S. Citizenship and Immigration Services. Optional Checklist for Form I-765 (c)(3)(C) Filings Processing times vary, so file early.
The STEM Extension
If your degree is in a qualifying science, technology, engineering, or math field from an SEVP-certified school, you can apply for a 24-month extension on top of your 12 months of post-completion OPT. Your employer must use E-Verify, and both of you must complete a formal training plan on Form I-983. STEM graduates can therefore reach up to 36 months of practical work experience.14Study in the States. F-1 Optional Practical Training (OPT)
Severe Economic Hardship
If your finances change dramatically after arrival (currency devaluation, loss of a scholarship, unexpected medical costs), you may qualify for off-campus work authorization under the severe economic hardship provision. You need at least one full academic year in F-1 status and good academic standing. Your DSO recommends you on a new I-20, and you file Form I-765. Approved EADs run up to a year at a time and cannot extend past your expected program completion date.15U.S. Citizenship and Immigration Services. Chapter 6 – Employment
Bringing Family on F-2 Visas
Your spouse and unmarried children under 21 can join you on F-2 dependent visas. Each dependent needs a separate I-20 issued in their name and their own F-2 visa stamp. Their status is tied to yours: if you fall out of F-1, their F-2 status ends.
F-2 dependents cannot accept any employment in the United States.10eCFR. 8 CFR 214.2 – Special Requirements for Admission, Extension, and Maintenance of Status An F-2 spouse can take classes part-time only; a full course of study requires switching to F-1, M-1, or J-1. F-2 children can attend K–12 school full-time but face the same part-time limit at the college level.
Taxes and a Social Security Number
Holding an F-1 does not exempt you from U.S. tax filing. For your first five calendar years in the country, you are generally a nonresident alien for tax purposes because you are exempt from the Substantial Presence Test.16Internal Revenue Service. Foreign Student Liability for Social Security and Medicare Taxes After five years, you may become a resident alien if you meet the test, which changes how your worldwide income is taxed.
Even with no U.S. income, you must file IRS Form 8843 every year to document your exempt status. If you had any U.S.-sourced income, including on-campus wages, a taxable scholarship, or treaty-exempt income, also file Form 1040-NR. The deadline is April 15 if you had wages subject to withholding, or June 15 if you did not.17Internal Revenue Service. Publication 519 – U.S. Tax Guide for Aliens
You can get a Social Security number only if you have authorized employment. With an on-campus job, CPT, or OPT, you can apply at your local SSA office with your passport, I-94, I-20, and proof of work authorization.18Social Security Administration. Foreign Workers and Social Security Numbers Without work authorization, SSA will not issue a number, though you may be able to get an Individual Taxpayer Identification Number from the IRS for tax filing purposes.
When Your Program Ends
The 60-Day Grace Period
After you complete your program or finish authorized post-completion OPT, you get 60 days to prepare to leave, transfer to another SEVP school, or file a change-of-status application with USCIS. You cannot work during this window, and if you leave the U.S. before the 60 days are up, the remaining time is forfeited.19Department of Homeland Security. Complete Program
Cap-Gap Extension for H-1B Transition
If an employer files an H-1B petition on your behalf while you are still on OPT, your F-1 status and work authorization can extend automatically past their normal expiration. This “cap-gap” bridges the time between your OPT end date and October 1, when H-1B employment typically begins. You must be in valid F-1 status on the filing date, and USCIS must issue a receipt for the H-1B petition.20Study in the States. H-1B Status and the Cap Gap Extension
Travel warning: if you leave the country before USCIS approves the H-1B change of status, the agency treats the petition as abandoned and your cap-gap extension ends.
What Happens If You Overstay
Failing to depart or take legal action within the 60-day grace period puts you out of status. F-1 students who violate a term of status, such as working without authorization or dropping below a full course load, face a five-year bar on re-entering the United States.21Office of the Law Revision Counsel. 8 USC 1182 – Inadmissible Aliens Separately, more than 180 days of unlawful presence followed by departure triggers a three-year bar, and a full year or more triggers a ten-year bar. Bars can stack, and waivers are hard to get. If your program is ending and your next step is unclear, talk to your DSO or an immigration attorney before the grace period runs out.
