Use current official instructions and the actual applicant or corporate proposal, with any differences from summaries identified.
Check what the summary leaves out
Confirm obligations, family terms and actual process stage. A shortened explanation should not replace the official terms governing the concrete decision.
A dated, complete copy of the official program page and FAQ, the application confirmation and receipt, the payment records and any correspondence, so that the terms relied on can be shown later if the published terms change. The most useful documentary habit here is unglamorous: take a dated copy of the official programme page and questions-and-answers, and of the executive order, at the moment of making a decision. Keep a current official programme record, the applicant’s identity and civil documents, evidence for the underlying immigrant classification, and payment documentation in separate sections. A first review builds an evidence matrix with an official-program copy, civil records, payment-source records, and the materials needed for the chosen EB category. Clarify discrepancies through the proper channel instead of using a third-party summary as proof of either eligibility or a decision.
