I spent my entire life up to my mid 20s in Spanish congregations in Texas and the number of illegal immigrants was nowhere near 90%.
Actually right now I’m about 2 miles from the border of Juarez Mexico. The city I’m in has a population close to a million by now. The U. S. Census tells us that Texas has about 38% Hispanic or Latino. But where I’m at, the percentage of Hispanic or Latino in 2013 was over 81%. The local news said a few weeks ago that it pretty close to 90% now
During the drug wars in Juarez a few years back I was attending the Spanish Congregation and I saw literally hundreds and hundreds of Spanish brothers and sisters cross the river and start attending the congregations in El Paso. Last I heard about 2 years ago there is over 90 congregations in Spanish and only about 15 -20 English. Most of the jw brothers cannot be MS or Elders because they are illegal. These Spanish brothers stayed here after the drug wars. They started landscaping, construction, pool cleaning and repair business. The Women started house cleaning businesses. Many of them do well and make lots of money but they are illegally in the country.
The WT has had the Spanish conventions here for the past few years. Sometimes they have 3 summer conventions in the area because these Spanish JWs cannot travel because they will get caught in the inspections points crossing the State. But since they have money to contribute and there is about 90 congregations in the City, there is no way that WT will not exploit that.
So just counting the Spanish congregations in my area, we are talking 70k to 100k Spanish Publishers. If they were forced to go back to Juarez Mexico, it would affect the whole JW population and Kingdom Halls in my area.
The Spanish JWs here are very concerned that Donald Trump might become President. Many of them have business making over 100k a year. Compared to $150 a month if they go back That does not include the Non-jws that are here in this city illegally.
