My friend opened a wedding photography studio in Canada. He asked me to work there. I studied post-production. How can I get a visa? Do I need a deposit?

Your friend will apply to you for a job invitation through the Canadian Labor Department. But he needs to prove that no one in Canada does this job. Then, after approval, you can find foreign workers and sign contracts with you.

You take this contract, prepare the materials and apply for a visa.

You don't need a deposit because you have a job.
