It should reflect the real plan for the person’s services, supported by the organization’s circumstances and relevant records. A promise copied into a letter without a factual basis is not a reliable explanation.
Connect the assignment to continuing operations
Identify the work expected abroad and distinguish it from the U.S. duties. Have the evidence assessed alongside ownership, corporate relationships and the qualifying employment history rather than treating the return paragraph as a stand-alone cure.
Ranked by weight, the records that carry the return commitment are the ones the company generates for its own purposes: board minutes or a written resolution recording the assignment, correspondence with the foreign entity about coverage during the absence, and any budget or staffing document showing the function continuing. A support letter summarising these is useful; a support letter standing alone is thin. The failure worth naming is the recycled paragraph, being text lifted from an earlier petition or a template that describes a return position which does not correspond to the company's current structure.
Read the letter beside the corporate records and ask whether a reader who saw only the records would recognise the description. Where the letter says more than the records support, either produce the missing record or reduce the claim to what is true. Do not sign a letter that nobody in the organization could explain under questioning.
