A visa violation occurs when an individual does not adhere to the terms and conditions of their visa. This can include overstaying the allowed duration, working without authorization, or failing to maintain the status required by the visa type. Such violations can lead to serious consequences, including deportation or bans on re-entering the country. Countries have specific laws and regulations regarding visas, and it is essential for travelers to understand these rules. Organizations like the U.S. Citizenship and Immigration Services (USCIS) provide guidelines to help individuals comply with their visa requirements and avoid potential violations.
