Spanish in Hialeah and Spanish in Doral are two different rooms
Country of origin decides the vocabulary, the status and the fear, so a post written for the county average lands in none of those rooms.
Miami-Dade is majority foreign-born, and the Spanish spoken across it arrives from many countries at once. A Cuban family in Hialeah, a Venezuelan family in Doral and a Nicaraguan family in Kendall use different words for the same status and follow different news entirely.
The statuses cluster by origin as well. Parole, temporary protection, asylum matters of very different ages: two families a mile apart are watching questions that barely touch, so a general immigration update lands as background noise in both houses.
Write the situation rather than the nationality. A clear piece about what happens when a temporary status is not renewed reaches everyone it applies to, while a post addressed to one national group tells every other reader the firm is not for them, and it ages badly the week policy moves.
Take the vocabulary from your own intake. The phrases callers actually say are rarely the phrases printed on a government page, and staff hear the real ones every day. Borrowing them costs nothing and is the difference between sounding local and sounding translated.
