Hello, please, what are the procedures and what do I need to get my Spanish passport for 1 time? Thank you

If you have already received your Spanish Birth Certificate you have 2 options to request your passport: prior appointment or present at the Consulate General at 8:00 AM to manage your passport, remember to bring original and copy of all your documents and a money order for 33.00 Dollars.

Look on the website of the consulate. It's all very well detailed
