I live in Lebanon and I made an account on Linkedin. I got a work offer from a company from Canada. They asked me questions about my education, marital status and if I have 12,000$ in my account to support myself if I were to go to Canada. They asked if I have a visa card as well as what the first 6 digits are.
Why would they ask for the first 6 digits and is it safe to give him those digits?
