So for the visitor visa I'm asked to attach my birth certificate and I had a few questions about it. Since my country is Spanish speaking, my birth certificate is in Spanish and I was wondering if I should translate it.
Also I was wondering if a copy was good enough for the application or if it should be an original?
Yes sir. You need to have a professional translate that and they need to sign the document. If you're applying through a paper application, what i've read is you need to have it notarized. All these are indicated in the instructions so you can check them to be sure.
