Visa requirements are universal, regardless of your nation of origin. However, these requirements vary by country, and because each visa represents a unique relationship between nations, they are specific to each case.

There are two broad categories of visas applicable to all countries:

  • Non-immigrant visas (which do not result in naturalization) 
  • Immigrant visas (you do become a citizen of that country)

These two broad categories are shown in terms of four subtypes of visas:

  • The Tourist Visa is the most frequently requested visa in the world. The Tourist visa is what it sounds like and allows the following activities:
  • Tourism
  • Visiting friends and family
  • Attending a wedding
  • Receiving medical treatment
  • Participating in amateur musical, sporting, and musical competitions
  • Short-term study
  • Business or Work Visa.

There are non-immigrant and immigrant visas available for business trips and paid employment.

Government authorities issue business visas to travelers who intend to engage in lawful business activities and attend meetings that do not involve paid labor or employment in a particular nation.

On a business visa, frequent activities include:

  • Attending meetings
  • Attending business events/conferences
  • Investigating business ventures and opportunities

The most important aspect of business visas is that they typically involve only business logistics and relationships, not actual labor or services.

However, the privileges granted to a business visa holder vary from country to country. For example, some countries permit holders of business visas to install goods (hardware, machinery) after a sale, whereas other countries may require a work permit for the same service. Some countries even allow citizens of certain countries to engage in permitted business activities without requiring a visa.

In addition, business visas differ from work visas in that they are typically granted for a temporary, short-term period, whereas work permits are typically granted for longer durations.

Numerous business visas are valid for 30 to 90 days within 180 days. However, some business visas are issued for periods as short as 15 days or as long as 90 days.

In addition, the conditions of entry frequently vary, with some business visas allowing multiple entries into the country of issuance during the visa’s validity period.

Government authorities issue work visas to foreign nationals who earn income or compensation through work performed abroad or who provide temporary services in the host country. Productive labor is defined differently depending on the activity and the host country.

Common motives for requesting a work visa:

  • Acquiring a full-time or part-time job
  • Participating in a project
  • Working under a contract
  • Being transferred from a host organization to an affiliated organization in another country

Work visas permit foreign nationals to engage in paid work, contracted labor, or any other activity that a country deems to require an income or compensation. Some work visas are valid for six months, while others are valid for a year or longer.

  • Visas for students wishing to study abroad

A student visa is an endorsement added to a passport that allows international students to enrol in a country’s recognized educational institutions. Any prospective student wishing to pursue higher education in another nation is required to obtain a student visa from that nation.

A student visa issued for full-time degree-level study permits a maximum of 20 hours of work per week during the academic term. This is a maximum of 20 hours per week for one or more organisations, whether paid or unpaid. The 20 hours cannot be spread over a more extended period.

  • Immigration and naturalisation visas (including by marriage)

Foreign nationals who intend to live permanently in a country other than their country of birth are issued immigrant visas.

Naturalisation is known as the legal process of acquiring a new nationality.

These four sub-types apply to every country worldwide, though the requirements can vary greatly, mainly based on the country you’re applying to.

Obtaining a tourist visa is likely the most straightforward option unless you intend to remain in a country for an extended period.
