Yes, a job offer is mandatory before applying for a Switzerland Work Visa. The Swiss employer plays a central role in the process, as they must apply to cantonal authorities on behalf of the applicant. Employers must prove that the position could not be filled by a Swiss or EU/EFTA citizen, following the principle of giving preference to domestic and European labor. Only once the employer receives approval can the applicant proceed with their visa application at the Swiss Embassy in Dubai. Without a valid employment contract, individuals cannot directly apply for a work visa.
