For example, I'm a citizen of Spain, but I was born in Portugal and I have birth certificates (BC) from both countries.
However, my first names are different on Portuguese and Spanish BC, because my parents changed my name after they applied for Portuguese BC and before getting Spanish BC.
I've always used the name on my Spanish BC everywhere (passport, school records, study/work permits, T4, etc.). In fact, I almost forgot that the Portuguese BC exists...
In this case, should I declare that I've used other names and attach a letter of explanation saying that the name exists only on my birth certificate and isn't used anywhere else?
