Visas have become an essential part of international travel and immigration in the modern world. They not only ensure the security and sovereignty of countries, but also promote global cultural, economic and educational exchange. A visa is a document or permission that gives a person the right to enter, reside or perform specific activities in a foreign country. The concept traces its history back to ancient civilizations, when empires such as Egypt, Rome and India issued letters or passes to travelers and traders to allow them entry. “Safe Conduct” letters were common in medieval Europe, guaranteeing ambassadors and merchants safe travel. But the modern visa system developed in the 20th century, when countries began making passports and visas mandatory to protect their borders during World War I. In 1920, the League of Nations introduced a standardized system of passports and visas, which played a key role in organizing international travel. After World War II, the United Nations and the International Civil Aviation Organization (ICAO) further refined these rules. Today, the main purpose of visas is to ensure the security of countries, prevent illegal immigration, and verify the identity and purpose of travelers.
Types of Visas
There are several types of visas, depending on the purpose and duration of the visit. Tourist visas are designed for people who wish to visit a country for holidays, sightseeing or cultural experiences. The duration usually ranges from a few weeks to six months. For example, countries like Thailand and Maldives offer tourist visas on arrival to Indian travellers.
Student visas are for students who wish to study abroad. They are valid for the duration of the course and in some countries, there is also an option of a work permit after studies. Student visas are in high demand in countries like Canada, Australia and the UK.
Work visas are for people who wish to work abroad and require sponsorship or a job offer from an employer. For example, the US H-1B visa is popular among technical and professional workers.
Business visas are issued for business meetings, conferences or other business activities and are usually short-term, with no work permission.
A transit visa is for travellers who travel through one country to a third country, and is valid for a few hours to a few days, such as in Dubai or Singapore.
A diplomatic visa is for diplomats, government officials and representatives of international organisations who travel on official business.
A medical visa is for patients who wish to seek medical treatment abroad. India itself is a major hub for medical tourism, but Indian citizens also travel to countries such as Thailand and Singapore on medical visas.
A family visa is for those who wish to bring their family members, such as spouses or children, abroad, and is usually available to residents or citizens.
An immigrant visa is for those who wish to settle in a country permanently, such as the US Green Card or Canada’s Express Entry programme.
Also, an electronic visa or e-visa is a digital visa that is obtained through an online application. Countries like India, Australia, and Türkiye offer it, making the application process simple and fast.
Application Process
The importance of visa can be understood from many perspectives. It helps protect countries from illegal entry, terrorism and criminal activities, thereby strengthening national security. Tourist and business visas promote tourism and trade, which is beneficial for the economy of any country. It gives people an opportunity to understand the culture, traditions and lifestyle of different countries, thereby promoting cultural exchange. Student visas give students an opportunity to receive world-class education, which contributes to their career and the development of the country. Also, visa policies help control immigration, thereby maintaining a balance between population and resources.
The visa application process varies depending on the country and visa type, but some common steps apply everywhere. Most countries require you to fill out an online form for a visa, while some require you to submit an application at an embassy or visa center. Documents such as a valid passport, passport size photo, bank statement, travel insurance, hotel booking, flight ticket and invitation letter must be submitted with the application. Many countries require biometric data, such as fingerprints and digital photos. Some visas, such as US and Schengen visas, require an interview in which the applicant must explain their travel purpose and background in detail. Each visa has a fixed fee, which varies depending on the country and visa type. Visa processing can take anywhere from a few days to several weeks, so it is important to apply on time.
Visa Free Travel
Visa-free travel options for Indian passport holders are limited until 2025. According to the Henley Passport Index 2024, the Indian passport is ranked 85th and Indian citizens can travel visa-free or with visa on arrival to only 60 countries. These include Nepal, Bhutan, Maldives, Mauritius, Seychelles, Indonesia, Thailand, Sri Lanka, Jamaica, Cambodia, Kenya, Fiji and some Caribbean countries.
Countries such as Australia, Turkey, Sri Lanka and the UAE offer e-visas for Indians, which simplifies the application process. Countries such as Thailand, Maldives and Mauritius offer visas on arrival. However, the US, UK, Canada, Australia and Schengen countries require Indian citizens to obtain visas in advance. These countries have strict screening and document checking processes.
Getting US visas, such as B1/B2 and H-1B, is particularly challenging, as it involves intense screening and interviews. UK visas require financial stability, travel purpose and background checks, with Tier 4 student visas and Tier 2 work visas being popular. Canada’s Express Entry system is point-based, evaluating education, work experience and language skills. Australia’s Skilled Migration Program is also based on a point system. Schengen visas are required for travel to 26 European countries and require accurate documentation and travel planning. Saudi Arabia has introduced tourist visas in recent years, but rules are still strict for non-Muslims.
Obtaining a visa comes with several challenges, such as complex procedures, long processing times and fear of rejection. Indian citizens often have difficulty proving financial stability and travel history. These challenges can be addressed by submitting accurate and complete documents, taking help from visa consultants, buying travel insurance and applying on time. Travel insurance is mandatory in many countries and it reduces the risk of rejection.
Overall, the visa system is the basis of international travel and immigration in the modern world. It helps countries control their security, economy and cultural exchange. Different types of visas cater to the diverse needs of travellers, but each country has its own policies and procedures. Visa-free travel options for Indian citizens are limited, but e-Visa and Visa on Arrival have simplified the process to a great extent. Getting a visa can be easy with the right documentation, timely application and following the rules. Visas not only allow travel, but also promote global integration and cooperation, which is vitally important in today’s interconnected world.
