Read the excerpt from Meir y Teran about Mexican worries of American expansion in Texas
Meir y Teran to Pueblo Viejo, Nov 24, 1829
The department of Texas is contiguous to the most avid nation in the world. The North Americans have conquered whatever territory adjoins them. In less than half a century, they have become masters of extensive colonies which formerly belonged to Spain and France, and of even more spacious territories from which have disappeared the former owners, the Indian tribes. There is no Power like that to the north, which by silent means, has made conquests of momentous importance. Such dexterity, such constancy in their designs, such uniformity of means of execution which always are completely successful, arouses admiration. Instead of armies, battles, or invasions, which make a great noise and for the most part are unsuccessful, these men lay hands on means, which, if considered one by one, would be rejected as slow, ineffective, and at times palpably absurd. …. The territory against which these machinations are directed, and which has usually remained unsettled, begins to be visited by adventurers and empresarios; some of these take up their residence in the country, pretending that their location has no bearing upon the question of their government’s claim or the boundary disputes; shortly, some of these forerunners develop an interest which complicates the political administration of the coveted territory; complaints, even threats, begin to be heard, working on the loyalty of the legitimate settlers, discrediting the efficiency of the existing authority and administration; and the matter having arrived at this stage—which is precisely that of Texas at this moment—diplomatic maneuvers begin: They incite uprisings in the territory in question and usually manifest a deep concern for the rights of the inhabitants.

Tejano elite favors American immigration
What shall we say of the law of April 6, 1830? It absolutely prohibits immigrants from North America coming into Texas, but there are not enough troops to enforce it; so the result is that desirable immigrants are kept out because they will not violate the law, while the undesirable, having nothing to lose, come in freely. The industrious, honest North American settlers have made great improvements in the past seven or eight years. They have raised cotton and cane and erected gins and sawmills. Their industry has made them comfortable and independent, while the Mexican settlements, depending on the pay of the soldiers among them for money, have lagged far behind. Among the Mexican settlements even the miserable manufacture of blankets, hats and shoes has never been established, and we must buy them either from foreigners or from the interior, 200 or 300 leagues distant. We have had a loom in Bexar for two years, but the inhabitants of Goliad and Nacogdoches know nothing of this ingenious machine, nor even how to make a sombrero.
The advantages of liberal North American immigration are innumerable: (1) The colonists would afford a source of supply for the native inhabitants. (2) They would protect the interior from Indian invasions. (3) They would develop roads and commerce to New Orleans and New Mexico. (4) Moreover, the ideas of government held by North Americans are in general better adapted to those of the Mexicans than are the ideas of European immigrants.
