To enter Turkey, children from Saudi Arabia must obtain a Turkey visa, including an internet visa or e-Visa. Children's visa requirements are essentially the same as those for adults.
When applying for a Turkey visa, parents or legal guardians can file separate visa applications for their children. The application process may necessitate the same supporting documentation as for adults, such as a passport, pictures, and travel plan.
It is important to note, however, that visa restrictions can change over time. For the most accurate and up-to-date information on visa requirements for children from Saudi Arabia traveling to Turkey, it is important to check the Turkish government's official website or speak with the relevant Turkish embassy or consulate.
