Explain its actual effect on the applicant’s duties and authority. Review any material change before relying on documents prepared under the earlier terms.
Use the rules that govern the proposed work
Distinguish an agreement under negotiation from one already effective. Avoid describing powers that have ended or treating proposed changes as current facts. Fix one date and describe everything relative to it: the date the petition is filed.
Terms that took effect before that date are current facts. Terms still under negotiation are proposals, and describing a proposal as though it were in force is the error that most often produces a request for evidence in this kind of case. Where a change lands between filing and the assignment starting, say so plainly rather than allowing the earlier description to stand.
Hypothetical example: a renewed agreement moves scheduling authority from the individual manager to a planning committee, and the support letter, drafted three months earlier, still describes the applicant as setting schedules alone. The correction is short and costs nothing at the time; discovered later, it puts the accuracy of the whole description in question. Keep a dated note of what changed, when it took effect and which paragraphs of the letter it touches, and review whether the qualifying year abroad or the corporate relationship is affected by any reorganisation that accompanied the new terms.
