The documents that show authority rather than branding: the countersigned offer, payroll and withholding registration, the reporting line, and any secondment or intra-group services agreement. Follow the actual document requirements in the USCIS instructions for the I-140G and the official portal rather than assuming a recent registry extract is always needed.
Building the affiliate-B evidence set without contradicting entity A
Keep the two entities distinguishable in the file. If an agreement between them explains why the role moved, include the operative clauses rather than a summary. Foreign-language documents filed with USCIS need a full certified English translation; consular language requirements can differ, so check the specific post's instructions.
Missing or unclear records can lead to a request for evidence or a refusal, so resolve gaps before filing. Assemble the evidence in the order in which it stops being available. Internal approvals, message threads and draft agreements circulating during a reorganisation are often the clearest evidence of which entity was directing the role, and they are also the first things removed when systems are consolidated.
Ask for copies while the change is still in progress. Hypothetical example: a sponsored engineer joining a group that owns a packaging-line installer needs the secondment agreement explaining the move, and the only signed copy sat with a manager whose account was closed at the transition. Follow the document requirements in the official instructions rather than assuming which records are needed, and where foreign-language documents go to USCIS, plan for a complete certified English translation.
