Do i file for her papers? Or should i give it more time?

Hi Patriot 101. Get to know her more and see her in Colombia if it is safe to do so. She can only come here thru fiancee visa and you need to show more proof (pictures together, letters etc) that you and her have a solid relationship and not just for immigration purposes.

This sounds very fishy to me. So definitely give it more time and make sure she is who you think she is. I'd hate for you to get taken advantage of and spend all that money/time to file that paperwork for her to take your for the proverbial ride.
She sounds very pushy to me and that makes red flags go up. Give it all the time you need. Good luck.

How should anyone here know better than you? And how can one make a generalization if men or women from any country are faithful? It is a individual thing. One should look at what one really has in common. And also look at what advantages one is getting out of a relationship. The simple fact is that many people live in poverty or at least not so good conditions and see a financial advantage to find a well off partner. Many foreigners think marrying an American or European will give them a better life. And even in western countries there are what we used to call "gold diggers".
