A "Visa Overstay" occurs when a person remains in a country beyond the expiration date of their visa. This situation can happen for various reasons, such as unexpected circumstances or a lack of awareness about the visa's validity. Overstaying can lead to legal consequences, including fines, deportation, or future entry bans. Countries often have specific rules regarding visa overstays. For instance, in the United States, individuals who overstay may face difficulties when applying for future visas or permanent residency. It is essential for travelers to keep track of their visa status to avoid these complications.
