Describe actual activity accurately. Do not invent employment to make the chronology look continuous.
Keep records consistent
Explain the real dates and available evidence. A candid gap is different from an unsupported claim that the applicant performed professional work throughout.
The letter should identify the U.S. employer, state that the position is that of an agronomist, describe the professional duties in specific terms, give the expected duration and salary, and confirm the applicant's degree. The officer works through a short sequence: citizenship, listed profession, qualification, prearranged professional employment and temporary intent. The applicant can supply credential and identity records, while the employer is the appropriate source for confirming the actual duties, reporting structure, and pay. If a staffing agency and an end client describe different responsibilities, ask them to reconcile the discrepancy rather than choosing whichever version sounds more favourable. The letter should identify the US or foreign employer, professional category, actual duties, worksite, compensation, intended period, and why the applicant meets that category’s precise education or licensing condition. Before the employer letter is drafted, the applicant should assemble dated employment records showing analytical duties, then decide whether the alternative is genuinely met. Where names or spellings differ across documents, bring the records that explain the difference rather than relying on an explanation at the counter.
