Foreign nationals are individuals who hold citizenship in a country other than the one they are currently residing in. They may travel, work, or study in a foreign country, often requiring specific documentation such as a visa or work permit to do so. The status of foreign nationals can vary significantly based on the laws of the host country. Some may enjoy certain rights and privileges, while others may face restrictions. Understanding the legal framework surrounding foreign nationals is crucial for both individuals and governments to ensure compliance and protect rights.
