The process of getting a visa typically involves making an application, providing necessary documentation, and submitting their biometric information like fingerprints and photographs. In some cases you may also need to attend an interview. Each country has its own set of requirements and criteria, which are all there to make sure that travellers follow the relevant regulations and respect local laws.

While the visa application process may seem complex, it is an integral and essential part of international travel. It not only helps people enter a country safely and easily, but it also helps countries manage the flow of visitors and keep everybody safe. 

Visas can be issued for short or longer periods of time, ranging from short-term stays to long-term residencies, depending on the purpose of the visit. The expiration date of your visa is really important, as overstaying a visa can result in serious legal consequences and stop you visiting the country in the future.

Some countries may expect you to provide additional documents, such as proof of financial stability or a letter of invitation. These requirements aim to ensure that travellers are responsible and have genuine reasons for their visit.
