No. Designation lets an entity sponsor pooled EB-5 investment; it is not approval of a specific project, an endorsement of the offering, or any financial guarantee. Your Form I-526E is still adjudicated on your own facts — lawful source and path of funds, capital genuinely at risk, and the required job creation.
Where the sponsor's status stops and your petition begins
Think of two separate files. One concerns the sponsor: whether it holds designation and complies with its own obligations. The other is yours: your money, your investment, your jobs. A problem in the first can damage the second, but designation alone does not establish that your petition qualifies; a separate project adjudication may also be relevant. Anything beyond these general points — how a specific structure will be assessed — needs current counsel review of the actual documents.
Lawful obtaining is examined through the donor: the file must show how the parents came to have the money, which for a farm sale means the deed, the title history, the quota records and the tax returns around the disposition. Current USCIS policy treats lawfully obtained loan proceeds contributed as cash, so they need not satisfy the personal-liability and personal-collateral test that applies when indebtedness itself is contributed.
