Candidates - Visas

I am an international student and I have just applied to IFP School. What are the steps to follow to apply for a visa?

The visa* procedure for an international student is launched when he/she is officially admitted by the School during the Admissions Board of May. An official letter of admission, signed by the Management of the School, is sent by mail. This letter allows you to begin the procedure with the consular services.
(*VLS/TS: long-stay visa valid as a student residence permit).
