Receive admission or enrolment confirmation from a licensed Omani higher-education or training institution.
Have the institution submit or support the student-visa application and provide the required approval or covering letter.
Provide a passport valid for at least twelve months, a personal photograph, enrolment evidence, and the required fees and supporting documents.
Complete the Royal Oman Police residence-card process after entry and keep the residence tied to the approved course and institution.
The official Study in Oman guidance describes a student visa valid for one to two years from entry, renewable with an institution letter while study continues.
This is a study route rather than a general work or remote-work permit. Any work permission should be confirmed separately with the institution and the relevant Omani authority.
