Colombians or Colombian-Americans or Latinos?

Like most Latino groups in the United States, they have problems of self-identity. I knew that there were quite a few Colombians in New York before reading this book because in Colombia when they talked about the Twin Towers they never failed to relate their connection with the disaster in that they had family or friends that had worked in the buildings.
As seen in the caravans, the Colombians are a very powerful group with strong dislike of the stereotypes that surround their country.
From personal accounts, I think that when a Colombian comes to the US they are more likely to stay and become citizens due to the problems back home. They still view their country in good terms, just it is not a safe place for them. This is becoming an even larger problem after all this turmoil between Venezuela and Ecuador and Colombia.
The thing I am confused on is with TLC aid program coming to Congress and the Congress undecided on what to do, why are the Colombians in the US not doing more to persuade them either way. It will bring money to Colombia, but at the same time it will take jobs away and in the end it is more beneficial to the United States. So why are they not doing anything to protect their pais? Is it just they are not in the media or that they are too worried about their own lives?
