Many foreigners get jobs in Turkey and travel to Turkey for work. Briefly, it works like this:
- Find a job in Turkey.
- Apply for the job.
- Get a job offer from the employer.
- Accept the job.
- Take the job offer or contract to a Turkish embassy to apply for a work visa.
- Pick up the work visa and travel to Turkey.
- Get your work permit from your employer and start working.
While you're applying for your work visa, your employer, in Turkey, will be applying for your work permit. These two things happen at the same time. You'll be providing documents such as your identity information and information about your skills and experience to your employer and to the Turkish embassy when you go to your appointment to apply for your work visa.
