Yo depronto voy a usa en diciembre

I'm soon going to go to work in December

Um, correct me if I'm wrong, but that line should translate to, "I'm going to the US soon, in December," shouldn't it?

The reason you found nothing is because a lot is spelled wrong.

Correct Spanish: Jaja, y has pensado venir a colombia? Yo depronto voy a usa en diciembre. Como me gustaria que conocieras todas las cosas hermosas de colombia, te mando besitos. Bye, y te quiero.

Ha ha! Have you thought of coming to Colombia? I'm soon going to go to work in December. I would like for you to get acquainted with all the beautiful things of Colombia. I send you kisses. Goodbye, and I love you.

Freeze, I believe you are correct because it says "yo depronto voy a usa en diciembre"

So yes, it should be "I'm going to the US soon, in December."

Good eye!

Yo de pronto voy a los Estados Unidos (USA) en diciembre

This would be the correct Spanish. De pronto are two words and this means:

at the moment my decision is......

This is from our dictionary:

por lo pronto adverbial phrase 1. for the time being (de momento); to start with (para empezar)

I know it defines de pronto as suddenly, but this is not the case here.

de pronto.

1. loc. adv. Col. posiblemente.
