Expect identity and civil documents for every person included, a full immigration and travel history, background and security information, and evidence going to the classification being used. The financial documents establish the payment; they do not establish eligibility.
Two files, and only one of them is about money
Applicants preparing for this route tend to assemble the financial side first because it is the part they have been told about. It is the smaller half. The larger half is the ordinary evidentiary burden of an employment-based immigrant case: identity and civil status documents with certified translations where they are not in English, a complete immigration and travel history, background information for each adult, and whatever the underlying classification requires by way of qualifications, achievements or an offer.
Because the programme is new, the precise document list is set by the official material and has been revised, so it should be taken from the source rather than from a summary. Anselm should also collect documents for each family member he intends to include at the same time, since a household application moves at the speed of its least prepared member and a missing civil document for a child can hold the whole file.
