Immigrants need money. How to spend money is the most affordable?

It depends on which country you immigrated to. Nowadays, it is generally like this:

North America: For example, the United States and Canada are generally investment immigrants, that is, you invest in a local project and make a profit, while gaining local legal status.

Europe: Generally speaking, you need to pay a sum of money to buy one or more local properties. With the recovery of European economy, European real estate generally appreciates, and you can also make a profit.

If you want to maximize the input and output as much as possible while immigrants gain the status of other countries, I suggest you make a concrete analysis according to different projects.
