How soon can the investment immigrant customers get the permanent green card and return the principal?

The question is incomplete. Investment immigrants exist in many countries, and each country is different. For example, in the United States, EB5 investment and China people have to wait in line for at least 10 years, and EB5 American law has long stipulated that this project is a risky investment project, whether the principal can be repaid or not, or if it is really risky, the investment must be risky. Australia 188b and 188c are two rare investment immigration projects in the market. Besides, they have been very safe for decades. To be sure, they can repay Australian government bonds. It is also unwilling to let the Australian government shut down. Besides, Australia is not much, and there is much gold, so we can't live any longer. Therefore, Australian investment immigrants are the most stable in the market, and according to the requirements of each project, they will definitely get green cards and principal. Of course, there are other countries with different national conditions, and many places are different.
