Some of these immigrants are hired by business owners in the states though the H-2A program which is a program that requires the employer to pay a certain amount of money in order to be guaranteed a worker. The H-2A program was modified in March of 2010 so that the workers would have documentation that they came to the United States to work.
In your oppinion, do you thing that illegal immigrants should be blamed for the United State's failing economy? Should the H-2A program be more selective about the immigrants that are coming to work in the U.S.?
