A student visa is a type of visa that allows individuals to study in a foreign country for a specific period. These visas are typically granted to students who have been accepted into a recognized educational institution and intend to pursue full-time studies. The requirements for obtaining a student visa vary depending on the country and the specific regulations of the educational institution. 

Generally, applicants must demonstrate proof of enrollment in a qualifying academic program, provide evidence of financial stability to cover tuition fees and living expenses, and sometimes show proficiency in the language of instruction.
