Final answer:
Immigrants may be sent back for not speaking English, not having enough money, or being young and not accompanied by a parent.
Step-by-step explanation:
One reason immigrants could be sent back to their homeland is if they couldn't speak English. Many countries have language requirements for immigrants to ensure they can integrate into society and communicate effectively. Another reason could be that they didn't have enough money. Some countries have financial requirements to ensure immigrants can support themselves and not become a burden on the social welfare system. Lastly, if they were too young and didn't come with a parent, they could be sent back. Some countries have policies in place to ensure the well-being and care of minors.
