Cuba and Mexico "Team up"

According to http://www.universityregister.org/index.php?option=com_content&task=view&id=806&Itemid=29 it sayed that Mexico is going to watch out so Cuban immigrants do not come to the United States. This is known as the "wet-foot dry-foot policy". It is said that this is a way to protect the economy from this problem. The other website I looked at, http://www.latimes.com/news/local/immigration/la-fg-mexcuba21-2008oct21,0,1064800.story said that this is most likely to prevent immigrants from coming here. It said that authorities have arrested about 2,000 illegal immigrants just this year. It also said that 11,ooo illegal immigrants (Cubans) made it to the United States this year.
