Vice President Joe Biden has added a stop in Guatemala on the eve of his visit to Latin America to discuss the growing problem of unaccompanied immigrants flowing into the United States' southwestern border, a senior administration official said late Sunday.

In Guatemala, Biden will attempt to dissuade Central American families from sending their children to the United States. Senior administration officials noted that Biden will emphasize, perhaps publicly, the inherent danger in the practice of turning children over to smugglers for a trek to America, and clarify that children who do make it to America are not eligible for deferred deportation. There's no light at the end of the tunnel for the unaccompanied minors, the official said.

Leaders from Honduras and El Salvador also will attend the meeting on Friday.

But before the hard work begins, Biden's going to take in some World Cup action in Brazil.

Sure, there may be doubts about America's prospects at the 2014 World Cup, but Biden's no fair-weather fan. He'll be cheering the U.S. national team from the stands in Monday's match against rival Ghana in Natal.

On Tuesday, Biden will meet in Brasilia with Brazilian President Dilma Rousseff. A senior administration official emphasized that the meeting is a reflection of the importance the Obama administration places on U.S.-Brazil relations, a relationship that has been strained by revelations last year that the National Security Agency was spying on Rousseff.

Biden also will meet with the presidents of Colombia and the Dominican Republic.
