I am aware that several countries have programs similar to the U.S. EB-5 program. This question/answer website is not an appropriate forum for an extensive comparison of those programs.
The statue governing the EB-5 Program provides that every immigrant investor must invest at least $1,000,000 in capital in a new commercial enterprise that creates not fewer than ten jobs. There is no country distinction. An exception exists if the immigrant invests in a “targeted employment area.” In such an area the requisite investment is reduced to $500,000. There are no different EB-5 requirements for different countries. Therefore, no emigrant has any advantage.
