The Mexican government is wanting settlers to come and populate Texas to protect it from uprisings from hostile Indigenous tribes and in our timeline the Mexican government invited Anglo-Americans to settle land in Texas if they learned Spanish and converted to Catholicism. But in a alternate timeline the Mexican government invites French and French Canadian settlers from Canada, Louisiana, and France as well as Anglo American settlers from the United States to go populate Texas with settlers to protect Northern Mexico from an uprising from Indigenous tribes such as the Comanche.
Protestant Anglo American settlement in Texas would be banned by the Mexican government because the Anglo Americans weren't willing to assimilate to their culture because they kept on being Protestants and continued to speak English and refusing to learn and speak Spanish. But French and French Canadian settlement in Texas would still be allowed because they were Catholic and even though some of the French and French Canadian settlers might not assimilate like the Anglo Americans would the Mexican government may discourage future French and French Canadian settlement or even tolerate some of the differences the French and French Canadians had such as speaking French instead of Spanish.
