In the colorful town of San Miguel de Allende, Mexico, with its temperate weather and stunning architecture, people spend their days relaxing on park benches that front La Parroquía, a towering neo-Gothic church of pink stone, which sits in El Centro, the center of town. People lose themselves strolling along the famed cobblestone sidewalks or grabbing a taco streetside and popping into a café. In the last few years, since Trump's first term, a growing number of these people have been American immigrants.
