Should America only change the language in Spanish?

For some undocumented migrants. About 20% of them are from countries other than the Spanish-speaking world, and not all undocumented migrants from Latin America speak fluent Spanish.

English is still the unifying language, and the sheer number of people upholds this status quo. Switching to Spanish does not help if the nation works so badly that all migrants leave. When we force ourselves to change our de facto language unnaturally, many people misunderstand and take so much time to do something because the communication comes to a standstill.
