CNN News:大篷车移民抵达美墨边境 申请美国庇护

AZUZ: And it's at one of those borders, the one between the U.S. and Mexico, that around 100 people from Central America are hoping to be granted asylum in the U.S. This is when someone is allowed to stay in America because they're at risk of being persecuted in their home country.
That might be due to their race, religion, nationality, political opinion, or membership in a certain group.
The 100 people hoping for asylum are from a caravan that once numbered about 1,200 and passed through Mexico last month. The caravan is an annual event designed to raise awareness about the conditions that Central American migrants face, and to help them seek asylum in other places.

Those who support the caravan say the migrants have valid fear of returning to their home countries and that they won't get justice there. Those who oppose the caravan like U.S. Vice President Mike Pence say they're a deliberate attempt to undermine the laws and sovereignty of the United States.
The dozens who've applied for asylum in America will probably have a long wait. The facility that processes people was already full before they arrived, and most Central American asylum applicants are rejected from both Mexico and the U.S.
It's a complicated process and a complicated issue like the issue of immigration itself in the United States.
