First clarify what evidence the review actually needs. A demonstration may show equipment operation without establishing the applicant’s qualifying knowledge or employment history.
Define the evidence purpose before spending
Separate professional preparation and official charges from production or demonstration costs. Any example should accurately explain relevant personal knowledge; expensive presentation alone does not satisfy the immigration requirements.
Recent USCIS fee rules provide small-employer rates for petitioners with 25 or fewer full-time-equivalent employees on parts of the I-129 fee structure, so the creamery should confirm its category and the current charges on the G-1055 schedule. Price the work needed to collect foreign-employment records, corporate-relationship documents, internal technical materials, translations, petition preparation, current government fees, and any optional expedited service. Where L-1B differs is in the professional effort: assembling proprietary documentation, drafting a technical narrative that a non-specialist adjudicator can follow, and responding to a request for evidence, which is frequent in this category. Decide which records would prove that knowledge even if the article disappeared: internal training, uncommon assignments, implementation history, and comparisons with ordinary staff may be more probative.
