Answer:
The General Mier y Terán Report concluded that the increase of immigration from the United States to Texas was a threat to keeping Texas in the Mexican federation.
Step-by-step explanation:
His recommendation was to ban immigration from the United States to Texas because it could lead Americans living in Mexico, who tended to isolate themselves from Mexican culture and people, to acquire too much power. Therefore, the law of April 6, 1830, banned immigration from the U.S. to Texas and imposed strong restrictions on trade.
