Hello dkg

I can´t advice you to answer yes to all questions as I do not know what are all the questions they will ask you. Swear and promise have very similar meanings, and it basically refers to your promise to pledge allegiance to the Spanish Crown and State and accept you duties and rights as a Spanish citizen.

I believe they have handed you a form to be filled out with your personal details, similar to a birth inscription, so you indicate your full given names, birth details, parents´details, even including your parents marriage details.

If you wish to discuss more details, please feel free to contact us by email.
