Good evening, I need to know if I need to register at the consulate to renew my passport and why do I want a passport to travel to Spain?

If you need consular registration to renew your passport, you have to print a form and fill it out, a passport photo proof of address, it is a 15-minute process. Then they give you a code and you make an appointment to renew your passport, if your passport is expired you need a valid birth certificate

I THINK YOU SHOULD HAVE THE CONSULAR REGISTRATION. TRY TO CALL THE CONSULATE AND THEY WILL TELL YOU. GOOD LUCK
