I am gonna post this question on this topic because I haven't been successful in the 'settlement' topic. As you may know, most people of Spanish speaking countries have two last names as family name (one from your father and the second one from your mother; both conform what is called here your family name; we called it last names). The thing is that initially when they (immigration) issued my first worker visa and work permit, they did it only with my first last name ('Perez'). But now that I have been granted permanent residence status, they have put both last names ('Perez Lopez'). I have applied for my new SIN card and they have put both last names as well. However, all my current documentation in Canada has only my first last name as my family name ('Perez'). Has anyone faced this problem before and how have you solved it?
