A visa application is a formal request submitted to a government authority for permission to enter, stay, or work in a foreign country. This process typically involves filling out specific forms, providing personal information, and submitting supporting documents such as a passport, photographs, and proof of financial stability. The requirements for a visa application can vary depending on the country and the type of visa being requested, such as a tourist, student, or work visa. Applicants may also need to attend an interview at a consulate or embassy as part of the evaluation process.
