Thank you for the question.
I was using both of those examples from Lexbase to show that, across the world, recruiters are practising immigration law. These are the only facts that I could find quickly to demonstrate that recruiters are practising immigration law abroad.
My submission is that they should not. Recruiters should recruit. Experts who are trained in immigration law should deal with immigration law. They are two different fields. But unfortunately, the immigration manual, at chapter IP 9, paragraph 5.4, indicates that recruiters may submit immigration applications or work permit applications.
