It is 7 a.m. on a cold, grey day in early March at the border crossing that connects Tijuana, Mexico, with San Diego, Calif.
Some 25 migrants have gathered on the sidewalk below the port of entry. These are families on a waiting list, each with an assigned number in the 3,000 range. If any of their numbers are called today, they’ll get a turn to cross to the United States, and at some point — in what will probably be a very brief visit — a chance to make their case for asylum.
