The 1951-mile-long international border between the United States and Mexico, which  
stretches from California to Texas, is the one that is most frequent across the globe.  
Even though the US government guards a sizable stretch of the border, about 800,000  
illegal Mexican immigrants manage to pass each year. These immigrants use a variety of  
strategies to enter the US, including, but not limited to: being smuggled across the  
border, traversing unguarded sections of the border on foot or by swimming, digging  
tunnels beneath the border, creating fictitious documents, or just overstaying a legal US  
visa. Long an unresolved issue, it has recently gained attention as the Congress and  
Senate negotiate an immigration bill that may significantly impact the present  
immigration situation in Mexico. This immigration bill may include various activities  
and policy reforms, including mass deportations, fast-track citizenship, and border wall  
construction.
