paragraph_text: Border Crossing Card violation
  
  A smaller number of illegal immigrants entered the United States legally using the Border Crossing Card, a card that authorizes border crossings into the US for a set amount of time. Border Crossing Card entry accounts for the vast majority of all registered non-immigrant entry into the United States—148 million out of 179 million total—but there is little hard data as to how much of the illegal immigrant population entered in this way. The Pew Hispanic Center estimates the number at around 250,000–500,000.
