Immigration documents are official papers required for individuals who wish to enter, stay, or work in a country other than their own. These documents can include visas, passports, and residency permits, which help governments track and manage the movement of people across borders. These documents serve various purposes, such as verifying identity, ensuring legal status, and allowing access to specific rights and services. For example, a visa may grant permission to work or study, while a passport serves as proof of nationality. Proper immigration documents are essential for a smooth transition into a new country.
