True. The EB-5, the religious visa programs and Conrad 30 waives for foreign physicians have been extended until 8 December 2017 pursuant to H.R. 601 – Continuing Appropriations Act, 2018 and Supplemental Appropriations for Disaster Relief Requirements Act, 2017.
Green card through EB-5 category continues to be an option for a specific category of investors, who have the money ($500,000 pr $1M) to invest. Under the US Constitution, the government cannot make laws that change vested rights retroactively. Therefore, if you have already invested and filed your EB-5 papers, I don't see why you need to worry about subsequent changes in the law.
Everyone with a running business outside the United States should seriously consider first the EB-1C category, which is considerably more attractive than EB-5 for several reasons. EB- 1C does not require a specific amount of investment, it requires instead only a business in the United States that is a subsidiary, branch, parent or affiliate of a foreign corporation transferring an executive or a managerial level employee to the United States. The managerial or executive employee receives an L-1A visa within a few weeks and can get a green card within a few months.
