Yes, in most cases, a tourist visa can be extended, though the process depends on the host country’s immigration laws. Extensions are typically granted for valid reasons, such as medical treatment, family visits, or unforeseen travel disruptions. Applicants usually need to file a request before their current visa expires, pay an extension fee, and provide supporting documentation. Not all visas are extendable, and approval is not guaranteed. It is always best to apply early and follow official procedures to maintain legal status during your stay.
