Types of US Visas: A Complete Overview
A clear breakdown of US visa categories — from B1/B2, F1, and J1 to EB-5 and the Green Card lottery — and which one matches your travel purpose.
Quick Answer
US visas fall into two broad categories — nonimmigrant visas for temporary travel and immigrant visas for permanent residence. B1/B2 (business/tourism), F1 (study), and J1 (exchange programs) are among the most common nonimmigrant categories, while EB-5 (investment) and the Diversity Visa lottery are the main routes to a Green Card. B1/B2 is by far the most-used category among Turkish citizens.

Every US visa falls into one of two broad families: nonimmigrant visas, for a temporary stay tied to a specific purpose, and immigrant visas, which lead to permanent residence. B1/B2 (business and tourism), F1 (academic study), and J1 (exchange programs) are the most familiar nonimmigrant categories, while EB-5 (investment) and the Diversity Visa lottery are the best-known paths to a Green Card. This guide maps out which category fits which travel purpose, what separates immigrant from nonimmigrant status, and the main options available — including specific notes for Turkish applicants, our largest audience, where the details vary by nationality.
Immigrant vs. Nonimmigrant: The Core Distinction
US visa categories split first along one line: does the visa authorize a temporary stay, or a permanent one?
Nonimmigrant visas allow entry for a limited period tied to a defined purpose — tourism, study, short-term business, or a specific program. The holder is expected to return home once that purpose is fulfilled, and each category has its own eligibility rules and permitted activities.
Immigrant visas lead to a Green Card — lawful permanent residence — typically through a family sponsor, an employer, an investment, or the annual Diversity Visa lottery. A Green Card is not itself a visa category; it’s the status you hold after an immigrant visa or an in-country adjustment of status is approved, and it opens a path to US citizenship over time.
Some nonimmigrant categories are dual intent, meaning the holder can pursue a Green Card without jeopardizing their nonimmigrant status — H1B is the clearest example. Most other categories, B1/B2 and F1 included, are not: showing an intent to immigrate can work against a nonimmigrant application.
The Most Common Nonimmigrant Visas
B1/B2: Short-Term Business & Tourism
The B1/B2 visa is, by a wide margin, the most widely used nonimmigrant category worldwide — including for Turkish citizens — covering tourism, family and friend visits, conferences, trade fairs, and short business meetings under a single combined visa. It’s typically issued for 10 years with multiple entries, though that validity period only governs how long you can request entry — actual stays are capped at up to 180 days per year, decided at the border. B1/B2 does not authorize working or studying in the US.
F1: Academic Study
The F1 visa is for full-time study at a SEVP-accredited US school, from intensive English programs through PhD study. Visa validity is tied to the length of your program, and F1 carries limited, clearly defined work rights — on-campus employment, CPT, and post-graduation OPT — rather than open work authorization.
J1: Exchange Visitor Programs
The J1 visa covers a wide range of Department of State-approved cultural and academic exchange programs, best known for Summer Work and Travel and Au Pair placements, but also covering research scholars, trainees, and teachers. J1 requires sponsorship through an approved program and, for certain categories, carries a two-year home-residency requirement before some other US visas become available.
C1/D: Transit & Crew
The C1/D visa is required for pilots, flight attendants, ship crew, and similar personnel entering the US on operational duty aboard a commercial aircraft or vessel, with stays capped at 29 days per entry regardless of the visa’s own validity.
H1B: Specialty Occupation Work
The H1B is the primary US work visa for positions requiring at least a bachelor’s degree in a specialized field, and it requires a sponsoring US employer. Because annual demand far exceeds the statutory quota, most years require a lottery among registered applicants. An initial H1B grant runs up to three years, extendable to a maximum of six — and as a dual intent visa, it doesn’t require you to demonstrate an intent to return home.
Other Nonimmigrant Categories
Beyond the visas above, a range of narrower categories cover specific travel purposes:
| Category | Visa Type | Covers |
|---|---|---|
| Work | H-2A | Temporary agricultural workers |
| Work | H-2B | Temporary non-agricultural/seasonal workers |
| Work | H-3 | Trainees in non-employment-focused programs |
| Work | L | Intracompany transferees |
| Work | O | Individuals of extraordinary ability (science, arts, sports, business) |
| Work | P | Athletes, artists, and entertainers |
| Work | Q | International cultural exchange programs |
| Work | R | Religious workers |
| Work | E-1/E-2 | Treaty traders and investors |
| Diplomatic/Official | A | Diplomats and foreign government officials |
| Diplomatic/Official | G1–G5 | International organization employees |
| Diplomatic/Official | NATO (1–6) | NATO personnel |
| Media | I | Journalists and media professionals |
| Transit/Crew | C | Transit through the US |
| Transit/Crew | D | Ship or aircraft crew |
| Special | T | Victims of human trafficking |
| Special | U | Victims of certain crimes |
| Family | V | Spouses and children of Green Card holders (specific categories) |
Turkey’s bilateral trade relationship with the US also makes the E-2 investor visa available to Turkish citizens who invest a substantial amount in a US business — an option not open to nationals of every country.
The Main Paths to a Green Card
Where a nonimmigrant visa authorizes a temporary stay, an immigrant visa leads to permanent residence. The most common routes are:
- Family sponsorship — through a US citizen or Green Card-holding relative
- Employment sponsorship — typically requiring a US employer and, for most categories, a labor certification process
- EB-5 investment — a Green Card through a qualifying investment in a US business that creates jobs
- The Diversity Visa (DV) lottery — an annual random-selection program open to applicants from countries with historically low rates of immigration to the US
Choosing the Right Category
Matching your actual purpose to the correct visa category is one of the most consequential decisions in the entire process — applying under the wrong category, or one that doesn’t match your stated intentions, is a common and avoidable cause of refusal. As a general guide: tourism and family visits call for B2, business travel for B1, university study for F1, exchange or work-and-travel programs for J1, and marriage-based immigration for K1 rather than any of the above.

Frequently Asked Questions
- How many main categories of US visas are there?
- Two: nonimmigrant visas, issued for a temporary stay tied to a specific purpose (B1/B2, F1, H1B, J1, and others), and immigrant visas, which lead to permanent residence (a Green Card) through a sponsor, employer, or a program like the Diversity Visa lottery.
- What's the difference between an immigrant and a nonimmigrant visa?
- A nonimmigrant visa permits a temporary stay for a defined purpose — generally up to 180 days at a time for B1/B2 — and the holder is expected to return home afterward. An immigrant visa grants lawful permanent residence (a Green Card) and can eventually lead to US citizenship.
- What is the most common US visa for Turkish citizens?
- The combined B1/B2 (business/tourism) visa is by far the most frequently issued category to Turkish citizens, used for everything from vacations and family visits to conferences and short business trips.
- Is a Green Card a visa?
- No. A Green Card is the lawful permanent resident status you receive as the outcome of an approved immigrant visa or adjustment-of-status process — not a visa category itself. It grants the right to live and work in the US indefinitely and creates a path to citizenship over time.
- What is a "dual intent" visa?
- Most nonimmigrant visas require you to intend to return home, but a small number of categories — H1B being the best-known example — are dual intent, meaning you can hold the visa while also pursuing a Green Card, without that undermining your nonimmigrant status.
- Which visa category matches which travel purpose?
- As a general guide, tourism and family visits fall under B2, business meetings or trade fairs under B1 (both usually combined as B1/B2), university study under F1, exchange or work-and-travel programs under J1, and marriage-based immigration under K1. Choosing the right category from the start matters for how smoothly your application proceeds.
