What is a Visa: Definition and All Types of Visas

Are you planning to study in the United States, or enjoying a vacation in Europe? When traveling to a foreign country, a visitor usually needs to apply for a visa. There are various visas, and the correct visa category will depend on the purpose of your visit.

Each country has its own immigration laws, so the requirements to travel differ from country to country. The types of visa and application processes, however, tend to be similar. Your visa category will depend on your travel purpose and the options available for your nationality.

This article explains the different types of visas, visa applications, and their requirements. Count on iVisa to help you find and prepare the documents you need to explore the world.

What is a visa?

A visa is an official document or stamp placed in a passport that grants the holder permission to enter, leave, or stay for a specified period of time in a foreign country. It is issued by the country the traveler wishes to visit, based on that country’s immigration and entry policies.

Obtaining a visa often involves an application process, where the applicant provides personal details, reasons for travel, and, in some cases, evidence of financial means or an invitation from a host in the destination country. The requirements and process for obtaining a visa can differ significantly from one country to another, reflecting each country’s security, economic, and diplomatic considerations. To see whether you need a travel visa for your next trip, check the visa requirements for your passport.

Visa categories according to the travel purpose

The purpose of your travel determines which type of visa you need. Requirements differ based on what you plan to do on your trip. Local authorities typically request documents to prove your travel intentions and that you can afford the costs. Here are some of the most common types of visas.

Tourist visa

When planning a vacation, travelers usually apply for a tourist visa online or through an embassy. Also known as visitor visas, tourist visas allow foreign nationals to stay in a country for leisure, to visit family and friends, or for other recreational purposes.

Tourist visas permit a short-term stay, ranging from 15 days to six months. The duration of stay and visa validity vary depending on the country and the nationalities eligible for the visa.

This is a non-immigrant visa, so it tends to have fewer requirements. Often, all you need is to show the intention to return to your home country. Immigration authorities usually ask for the following documents:

• A valid passport
• Passport-size photographs
• Proof of accommodation
• Return air ticket
• Sufficient funds to cover your expenses during the stay
• Travel itinerary

iVisa can help you apply online for tourist visas to visit many countries, whether you need a document in a few clicks or full guidance for a more complex visa, such as the B1/B2 to visit the U.S. Use the Visa Checker Tool to see whether a tourist visa is available for your next destination.

Business visa

This type of visa is for business travelers. You can apply for a business visa when your trip is for business purposes, such as attending a conference, meeting clients, or exploring business opportunities. Many countries include tourism and business trips in the same visa category, usually a tourist or visitor visa. In some cases, however, the government is more specific and requires a dedicated visa for business activities.

In many cases you can apply online, meeting just a few requirements, such as:

• A valid passport
• Passport-size photographs
• Business invitation letter from the host company
• Proof of accommodation
• Return air ticket
• Sufficient funds to cover your expenses during the stay

Medical visa

This visa is required for medical treatment. Some destinations are known for their medical care and create a special medical visa to manage the flow of travelers seeking health services. That is why you find visas such as the India Medical eVisa.

This category usually has medical requirements and asks for proof that the traveler intends to return home. It is common to provide the following documents:

• Medical certificate from a recognized medical institution
• Sufficient funds to cover your medical expenses during the stay

Work visa

A work visa allows legal employment in the country. It is issued to an applicant who has been offered a job in a foreign country and wishes to work there, so it falls under the immigrant visa categories.

Validity varies by country but usually ranges from one to three years. To apply, travelers need to prove they have a job and are qualified, typically by providing:

• A valid passport
• Passport-size photographs
• Work contract from the host company
• Proof of accommodation
• Return air ticket
• Sufficient funds to cover your expenses during the stay
• Educational qualifications and professional experience

You usually cannot apply online for a work visa. Check the application process and requirements for your work visa with your nearest embassy.

Student visa

Do you want to study abroad? You typically apply for a student visa with a consular officer. To get this document, you must be accepted to study at an educational institution in the country. Student visa validity changes depending on the country and the course duration.

Some countries allow you to work on a student visa, while others only permit study. To apply, you typically provide:

• A valid passport
• Passport-size photographs
• Acceptance letter from the educational institution
• Proof of accommodation
• Sufficient funds to cover your expenses during the stay
• Educational qualifications

Au pair visa

Some countries offer an au pair visa. This category is for applicants who want to reside legally in the country while caring for children in a program-approved host family. It is usually valid for 12 months. In the United States, for example, this visa is called a J-1 visa and is part of the Exchange Visitor Program.

The specific requirements for an au pair visa vary depending on the country where you plan to work. Common requirements include:

• A valid passport
• Signed contract with the host family
• Clear criminal record
• High school certificate
• Motivation letter
• Proof of language skills
• Being between 18 and 30 years of age

Nomad visa

Remote work is increasingly popular. With no need to go to an office, people work from anywhere with an internet connection. Many countries now offer a nomad visa, allowing these travelers a longer stay by presenting proof of regular income.

For example, you can work remotely with a Costa Rica Digital Nomad Visa, where you can fill out an online application in a few minutes. Requirements vary by country, but you may need some of the following documents:

• A valid passport
• Passport-size photographs
• Proof of remote work
• Proof of accommodation
• Proof of health insurance
• Proof of stable monthly income

Sponsor spouse visa

You landed a great job opportunity in another country, received your work visa, and now you need to bring your family with you. Many countries offer a sponsor spouse visa, a document issued to people who wish to join their spouse living and working in a foreign country. The Canada Sponsor Visa is one example.

To apply for this visa, you may need to provide some of the following documents:

• A valid passport
• Passport-size photographs
• Marriage certificate
• Proof that the spouse has sufficient funds to cover your expenses

Retirement visa

You have worked hard, and now you want to experience a different culture in another country. Some countries offer a retirement visa for people who wish to enjoy retirement abroad. A category like the Chile Retirement and Period Income Visa, for example, allows you to stay a year in the country if you can prove you have sufficient funds.

These are the usual requirements to apply for a retirement visa:

• Proof of retirement income
• Proof of accommodation
• Clear criminal record
• Sufficient funds to cover your expenses during the stay

Travel documents according to the application process

There are different ways to apply for the visas above. Each country determines the application process for each visa category, which may also change depending on the traveler’s nationality. For example, some nationals can visit the United States with the US ESTA, an electronic travel authorization they apply for online, while others must apply for a B1/B2 visa, a paper visa that requires a visa interview appointment for applicants older than 13 and younger than 80.

Use the Visa Checker Tool to see which document you need, and read more about the application processes below.

eVisa: electronic visa

Some countries have an electronic system to grant visas and manage the flow of visitors, usually for business and tourism. This is a quick and straightforward way to apply online. You fill out an application form in a few clicks and receive the document by email. It usually has fewer requirements and fast processing, the process is fully online, and the visa is linked to your passport electronically.

ETA: electronic travel authorization

An ETA (Electronic Travel Authorization) is similar to an eVisa but is often used for visa-exempt countries. It is an electronic approval issued in advance of your travel, allowing you to board a flight to the destination country. An ETA lets local authorities track visitors by collecting personal and travel information from digital forms submitted by travelers. On arrival, you may be required to show your ETA approval at immigration.

Visa on arrival

Some countries offer this visa as part of a visa waiver program, allowing eligible nationalities to get a visa on arrival. In some cases travelers fill out an online form before boarding; in others, the entire application happens at the airport. This can be inconvenient, since it often involves waiting in long lines, though it avoids the embassy’s paperwork beforehand. Make sure you have all the required documents, or you may be turned away before exploring the country.

Paper visa

In contrast to the other processes, a paper visa is a physical visa issued by a consulate or embassy and attached to a page of your passport. You may need to apply in person or by mail, and it can take several days or weeks to receive. A paper visa may also require additional documentation and an interview. It is usually the only option when you need to stay for longer periods, such as for work or study.
