Bulgaria's work visa process requires foreign nationals to secure employment before applying for a visa. Applicants must present a job offer from a Bulgarian employer, and the employer must first obtain a labor permit. The visa type varies based on the job and duration of stay. Long-term residents can apply for permanent residency. Additional documentation, such as proof of qualifications and health insurance, is often required. The process involves several steps, and specific details depend on individual circumstances. More info can be found on the Migrant Master website: https://migrantmaster.com/bulgaria-work-visa/
