Good afternoon, I need the authentication of a power to send it to Colombia, I have to ask for an appointment and what is its value? Thank you very much, because I've made several calls and they do not answer

I suggest appointment on the consulate page you have the document and the card and next they sell a card for paperwork for 24 dollars. That is what the authenticity is worth, or in publix you arrive and you take the turn it takes Medi hour approx. If you go direct you can stay all day and it is likely that you will not be served

Go personally with the document

Go there with the document ready, ID and money order $ 25.

I think it's best to go in person, I'm not sure but I think you don't need an appointment for that

if call not answered,it is better to go there and ask directly.
