The two that are most interesting to me are 5 and 6.
5. What country are you from?
If you have an accent, this may seem like an innocent question, but it’s illegal because it involves your national origin. Employers can’t legally inquire about your nationality, but they can ask if you’re authorized to work in a certain country.
6. Is English your first language?
It’s not the employers’ lawful right to know whether a language is your first language. In order to find out language proficiency, employers can ask you what other languages you read, speak or write fluently.
