This expert affidavit — which is cited several times in the motion for a preliminary injunction — outlines how this policy has reduced the flow of foreign investors and influenced the wait times for them. By counting spouses and children against the EB‑5 limit of about 10,000 green cards, the State Department has effectively reduced the quota for investors by almost two thirds. Rather than the full 10,000 going to investors, the government provided green cards to only about 3,500 investors in Fiscal Year 2017.
As a result of the policy, Chinese immigrant investors applying in FY 2018 will have to wait almost 16 years to receive permanent residence. About half of their children will reach adulthood during this time, which will cause them to “age out” (i.e. permanently lose their eligibility for green cards through their parents’ investments). Many have already had children age out. The lawsuit would seek to protect the remaining children from losing their opportunity to immigrate with their parents.
