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 a specific form, providing personal information, and submitting supporting documents such as a passport, photographs, and proof of financial stability. Once the application is submitted, it is reviewed by the relevant authorities, who may conduct interviews or request additional information. The outcome can result in either approval or denial of the visa, which determines whether the applicant can travel to the desired country.
