Mexico's President Anastasio Bustamante implements several measures in 1830 to make immigration less desirable for Anglo-Americans.

These measures follow the 1827 General Law of Expulsion whereby all foreign born people had been exiled from Mexico.

The General Law had been targeted at Spaniards, but by 1830, Americans are specifically targeted by rescinding the property tax law, which had exempted immigrants from paying taxes for ten years, and further increasing tariffs on goods entering Mexico from the United States, causing their prices to rise.

On April 6, 1830, Bustamante orders Texas to comply with the emancipation proclamation or face military intervention.

To circumvent the law, many Anglo colonists convert their slaves into indentured servants for life.

Others simply call their slaves indentured servants without legally changing their status.

Finally, he prohibits further immigration to Texas from the United States, although Anglos will still be welcome in other parts of Mexico.

The ban and other measures do not stop U.S. citizens from migrating to Texas by the thousands.
