For EB-5: the offering materials, the enterprise's organisational documents, the job-creation methodology, and the applicant's own source-of-funds trail. For any alternative: the governing legal text and the responsible agency's current published instructions, printed with the date accessed. Promotional comparisons prepared by anyone selling one of the routes should be set aside.
Build one table with dated citations
Give each row a requirement, each column a route, and each cell a source and a date. Empty cells are useful: they show where the comparison genuinely cannot be made yet. Note also that a regional centre designation is an administrative status, not a government endorsement or guarantee of the investment, so designation documents belong in the file as fact, not as reassurance about the project's merits.
Add one column to that table that changes how it reads: who is asserting each cell, and on what basis. A requirement stated in a statute or regulation, a figure published by a government body, a statement in an offering document prepared by a party with an interest in the outcome, and a claim made verbally by a promoter are four very different kinds of entry, and a table that records them all in the same typeface invites them to be weighed the same way. Mark the origin of every cell alongside its date.
Hypothetical example: a comparison table looks well evidenced until the source column is added, at which point half the cells on one side turn out to trace to material produced by parties connected to the offering rather than to any independent or official source.
