How should I fill the "First name" and "Last name" in an application if I have two given names and two last names? How should I fill this information if I have more than one given name and more than one last name?
For example, if my name is Juan Eduardo González Rodríguez. I have 2 given names: &quot;Juan&quot; and &quot;Eduardo&quot;, and I have 2 last names (The first one of my father and the second one of my mother because that how it is done in Mexico): &quot;González&quot; and &quot;Rodríguez&quot;.
Should I only write:

First name: Juan
Last name: González

or should it be

First name: Juan Eduardo
Last name: González Rodríguez (or González-Rodríguez)
I am in your exact same situation: Spanish name with 2+2. I have lived abroad for 6 years now, most of it in Ireland.

There is no way out of misunderstandings, I'm afraid, and your second last name will often be assumed to be your only family name.

Here is a recipe that has worked out for me so far:


For a non legally-critical situation, e.g. your name on a paper or a name tag at a conference, use your first last name only or hyphen both last names. You can then initialize your second (or even first) given names. People from English-speaking countries often have a middle name, so that's not a problem.
For legal and official stuff, use your full name as per your identity document so it cannot be used against you. If they get it flipped over it's their fault.
