US Nonimmigrant Visa Types: Categories, Eligibility, and Applying

US nonimmigrant visa types cover every foreign national who comes to the United States for a limited time and a specific purpose, as opposed to immigrants who intend to stay permanently. Federal law recognizes more than two dozen nonimmigrant classifications, each tied to a particular activity: tourism, business meetings, academic study, temporary work, cultural exchange, or protection as a crime victim.¹ A single principle runs through nearly all of them: the law presumes every applicant actually wants to stay permanently, and the burden falls on you to prove otherwise.²

Which category fits you depends on what you plan to do and how long you’ll be here. The sections below walk through the main groups.

Visitor Visas: B-1 and B-2

The B-1 covers short-term business travel — consulting with colleagues, attending conferences, negotiating contracts, settling an estate, or participating in brief training. It does not allow you to work for a U.S. employer or draw a salary from a domestic source.³ The B-2 handles tourism and personal travel: vacations, family visits, and medical treatment. Consular posts often issue a combined B-1/B-2 stamp so a single trip can include both.⁴

Both categories run headlong into Section 214(b) of the Immigration and Nationality Act. You have to convince the consular officer that your ties to your home country — stable employment, property, family obligations — are strong enough that you’ll leave when your visit ends. A 214(b) refusal is the single most common visitor visa denial, and there is no formal appeal. You can only reapply with stronger evidence.²

The Visa Waiver Program and ESTA

Citizens of 42 designated countries can skip the visa application entirely for short trips. The Visa Waiver Program permits tourism or business stays of up to 90 days without a visa, and participating countries include most of Western Europe, Japan, South Korea, Australia, and New Zealand.⁵ Instead of a visa, you apply online for an Electronic System for Travel Authorization (ESTA) before your trip. The application costs $40.27 and, once approved, lasts two years or until your passport expires, whichever comes first.⁶

The tradeoffs are real. You cannot extend beyond 90 days, you cannot change to another visa category while inside the country, and you waive most rights to contest removal. If you might need more than 90 days, apply for a B-1/B-2 instead.⁵

Student and Exchange Visitor Visas: F, M, and J

The F-1 visa is for academic students enrolled full-time at an accredited college, university, seminary, or private secondary school, and also covers English language training programs. Vocational students pursuing non-academic training — flight school, cosmetology, technical programs — use the M-1. Both require a full course load throughout enrollment.⁷

The J-1 visa is for exchange visitors participating in government-approved cultural and educational programs. The category is broad: research scholars, professors, au pairs, interns, and camp counselors all use it. Every J-1 participant needs a sponsoring organization overseeing their activities.⁸ Some J-1 holders face a two-year home residency requirement after their program ends, meaning they must return home for at least two years before qualifying for an H-1B, L-1, or immigrant visa. This restriction applies when the program was government-funded, when the visitor’s home country has designated the field as one where it needs skilled workers, or when the visitor came for graduate medical training.⁹

All F, M, and J applicants must be registered in the Student and Exchange Visitor Information System (SEVIS). Your school or program sponsor issues Form I-20 (students) or DS-2019 (exchange visitors) once they accept you and verify your finances. If your SEVIS record lapses because you drop below full-time enrollment or fail to report a change, your status terminates immediately.⁷ Before your visa interview, you also pay the SEVIS I-901 fee: $350 for F-1 and M-1, or $220 for most J-1 exchange visitors.¹⁰

Working as an F-1 Student: OPT and STEM OPT

F-1 students can apply for up to 12 months of Optional Practical Training in a job directly related to their field of study. You can use some or all of it before graduation (pre-completion OPT, part-time during the school year) or after (post-completion OPT, at least 20 hours per week). Your school’s international student office recommends the OPT in SEVIS, and you file Form I-765 with USCIS for an Employment Authorization Document.¹¹

Graduates with degrees in science, technology, engineering, or mathematics from accredited institutions can extend their OPT by 24 additional months, for a total of up to 36 months of work authorization. The STEM extension requires your employer to be enrolled in E-Verify, and you must file before your initial 12-month OPT expires. During the combined OPT period, you cannot accumulate more than 150 days of unemployment.¹²

Temporary Work Visas

Most work-based nonimmigrant visas require a U.S. employer to file Form I-129 (Petition for a Nonimmigrant Worker) with USCIS before you can apply. The employer is the petitioner; you are the beneficiary. Petition approval does not guarantee the visa — you still interview at a consular post — but the petition must come first.¹³

H-1B: Specialty Occupations

The H-1B is the main visa for professional jobs that require at least a bachelor’s degree in a specific field. Engineers, software developers, financial analysts, and architects commonly qualify. The employer must first obtain a certified Labor Condition Application from the Department of Labor, attesting that hiring a foreign worker will not undercut wages or working conditions for U.S. employees in similar positions.¹⁴

Congress caps new H-1B visas at 65,000 per fiscal year, with an additional 20,000 reserved for holders of a U.S. master’s degree or higher.¹⁵ Because demand far exceeds supply, USCIS runs an electronic registration and lottery each spring. Employers pay a $215 registration fee per beneficiary, and selected registrations move on to a full I-129 petition. Selection is weighted toward higher wage levels relative to the occupation and geographic area.¹⁶

H-1B holders are exempt from the presumption of immigrant intent that trips up visitor applicants. You can hold an H-1B and pursue permanent residency at the same time without jeopardizing your status, a concept called “dual intent.” L-1 holders share this exemption.²

L-1: Intracompany Transferees

The L-1 moves employees between offices of the same multinational company. You must have worked for the foreign branch, subsidiary, or affiliate for at least one continuous year within the past three. The L-1A is for managers and executives; the L-1B is for employees with specialized knowledge of the company’s products, services, or internal systems.¹⁷

O-1, P-1, and R-1

The O-1 is reserved for individuals with extraordinary ability or achievement — sustained national or international recognition in the sciences, arts, education, business, or athletics. The evidentiary bar is high, requiring documentation like major awards, published material about your work, or a record of commanding a high salary relative to peers.¹⁸ Athletes and entertainers performing at specific events or with internationally recognized groups use the P-1. Religious workers serving at nonprofit religious organizations qualify for the R-1, provided they have been members of the denomination for at least two years before the petition is filed.¹⁹

E-1 and E-2: Treaty Traders and Investors

These classifications are available only to nationals of countries that maintain a treaty of commerce with the United States. The E-1 (treaty trader) requires you to be engaged in substantial trade, more than half of which flows between the U.S. and your treaty country. The E-2 (treaty investor) requires you to invest a substantial amount of capital in a real, operating U.S. business and to play an active role in directing it. There is no fixed minimum investment; what counts as “substantial” depends on the proportional relationship between your investment and the total cost of the enterprise.²⁰

Dependent Family Members

Most work visa categories have a matching dependent classification for your spouse and unmarried children under 21 (H-4 for H-1B dependents, L-2 for L-1 dependents, and so on). Dependent children cannot work. Spouses in the L-2, E-1, E-2, and E-3 categories are automatically authorized to work based on their status and receive an I-94 with a code reflecting that authorization. H-4 spouses can apply for work authorization, but they must file separately for an Employment Authorization Document.²¹

Humanitarian Visas: U and T

The U visa protects victims of qualifying crimes — including domestic violence, sexual assault, kidnapping, and felony assault — who have suffered substantial physical or mental harm and are cooperating with law enforcement. It exists so victims will report crimes without fearing deportation.²² The T visa serves victims of severe human trafficking — people subjected to forced labor or commercial sexual exploitation through force, fraud, or coercion. Applicants must be physically present in the United States because of the trafficking and are generally expected to assist federal authorities with the investigation.²³

Who Can Be Disqualified

Qualifying for a visa category on paper is not the whole story. Certain factors make you inadmissible — legally barred from entry — regardless of category.

Health-Related Grounds

Applicants with certain communicable diseases are inadmissible. The designated conditions include active communicable tuberculosis, infectious syphilis, gonorrhea, and infectious leprosy. HIV is no longer on the list. For applicants examined overseas, additional diseases subject to quarantine orders or posing a public health emergency of international concern can also trigger inadmissibility.²⁴

Criminal Grounds

A conviction for a “crime involving moral turpitude” — a category covering fraud, theft, assault with intent to cause serious harm, forgery, and many other offenses — makes you inadmissible. So does any conviction related to controlled substances, regardless of whether the offense was a misdemeanor. Two or more convictions with combined sentences of five years or more are independently disqualifying, even if neither offense involves moral turpitude.²⁵

Fraud or Misrepresentation

Lying on a visa application or submitting fraudulent documents triggers a permanent bar. Any applicant who uses fraud or willfully misrepresents a material fact to obtain a visa or admission is inadmissible, with no expiration on the consequence. A waiver exists but is narrow, available primarily to immediate relatives of U.S. citizens or permanent residents who can show the denial would cause extreme hardship to the qualifying relative.²⁵

Public Charge

Consular officers evaluate whether you are likely to become primarily dependent on government assistance. This is a prospective, totality-of-the-circumstances assessment that weighs your age, health, financial resources, education, and family situation. Demonstrating sufficient funds for your stay and strong financial ties to your home country helps overcome the concern.

Applying: DS-160, Fees, and the Interview

Every nonimmigrant visa application starts with three baseline requirements: a valid passport, a qualifying photograph, and a completed DS-160.

Your passport must remain valid for at least six months beyond your intended stay. Some countries have bilateral agreements that exempt their nationals from this rule, but absent such an agreement, a passport expiring too soon will halt your application.²⁶ Your photo must be in color, taken within the last six months, against a plain white or off-white background. Eyeglasses are not allowed.²⁷

The DS-160 is the electronic application form for all nonimmigrant categories. You complete it online through the Consular Electronic Application Center, disclosing personal history, previous U.S. travel, past visa denials, employment history, and detailed travel plans including names and contact information for anyone you plan to visit or work with. Consular officers cross-reference your answers against federal databases; inconsistencies can delay or sink the case. Submitting the form generates a barcoded confirmation page you bring to your interview.²⁸

After the DS-160, you pay the nonrefundable Machine Readable Visa (MRV) application fee:

$185 for non-petition-based visas, including B (visitor), F and M (student), J (exchange visitor), and I (media). The U and T humanitarian visas are also in this tier despite being petition-based.
$205 for petition-based work visas in the H, L, O, P, Q, and R categories.

Payment must clear before you can schedule your interview. Students and exchange visitors also pay the separate SEVIS I-901 fee, bringing the upfront total for an F-1 applicant to $535 before any reciprocity fees.²⁹ Some nationalities pay an additional visa issuance fee based on what your home country charges Americans for a similar visa; the State Department publishes country-by-country reciprocity tables.³⁰

As of October 2025, nearly all applicants must attend an in-person interview, including those under 14 and over 79 (previously exempt). The main exceptions are certain B-1/B-2 and H-2A renewals filed within 12 months of the prior visa’s expiration.³¹ For visitor visas, expect pointed questions about your ties to your home country. For work visas, the officer focuses on whether the petition and your qualifications align.

After You Arrive: The I-94 and Maintaining Status

When you enter, Customs and Border Protection creates an electronic Form I-94 (Arrival/Departure Record) that serves as your official proof of lawful admission. It shows your entry date, the classification you were admitted under, and the date your authorized stay expires. You can retrieve and print your I-94 at any time through CBP’s website.³²

Your I-94 expiration date, not the visa stamp’s expiration date, controls how long you can stay. The stamp is an entry document — it governs how long you can use it to seek admission at the border. The I-94 governs your actual authorized period of presence. Confusing the two is one of the most common mistakes nonimmigrants make, and it leads directly to overstays.

Maintaining status also requires continuing to do the activity your visa authorized. A student who drops out or a worker whose employment ends and who takes no timely action falls out of status even if the I-94 date has not passed.

Extending or Changing Status

If you need more time or want to switch classifications, you file Form I-539 (Application to Extend/Change Nonimmigrant Status) with USCIS while still inside the United States. Filing before your current status expires is essential — USCIS recommends submitting at least 45 days before your I-94 expiration. To qualify, you must have been lawfully admitted, must not have violated the terms of your status, and your passport must remain valid through the new period requested. If your status expired before you file, USCIS will generally deny the request unless you can show the delay resulted from extraordinary circumstances beyond your control.³³

Employment-based categories like H-1B, L-1, O-1, and R-1 use a different form: the employer files Form I-129 rather than you filing I-539. Certain categories cannot extend or change status at all, including Visa Waiver Program entrants and C or D crew members.

Grace Period After Losing a Job

If your employment ends while you hold an H-1B, L-1, O-1, E-1, E-2, E-3, or TN visa, you get a grace period of up to 60 days (or until your I-94 expires, whichever comes first) to find a new employer willing to file a petition, change to another status, or prepare to leave. You cannot work during this window unless a new employer files on your behalf. The grace period ends immediately if you leave the country.³⁴

Consequences of Overstaying

Staying past your authorized period triggers escalating consequences. Accumulate more than 180 days but less than one year of unlawful presence and then depart, and you are barred from reentering the United States for three years. Accumulate one year or more and then depart, and the bar jumps to ten years.²⁵ These bars apply whether you leave on your own or are formally removed. Any existing visa in your passport is typically voided once an overstay is recorded, and you would have to apply for a new visa from outside the country while explaining the prior overstay to a skeptical consular officer.

Denials and Administrative Processing

A denial under Section 214(b) for failure to overcome the presumption of immigrant intent has no appeal. The refusal applies only to that application, and the consular section takes no further action once the case is closed. Your only option is to reapply, ideally with new evidence that addresses the identified weakness.²

Sometimes an application is not denied outright but placed in “administrative processing” under Section 221(g). The consular officer needs additional information — from you or from other sources — before making a decision. Processing has no fixed timeline and can take weeks or months. If the officer requested specific documents, you have one year from the refusal date to submit them. Miss that deadline and you start over with a new application and a new fee.³⁵
